Bugs Fixed in DataFlex 18.2

Runtime

Sending Refind_Records to a DDO may clear the file buffer of a DDO based on a system file

Bug 7082, reported by Clive Richmond
If Refind_Records is sent to a System file DDO and that DDO's current_record is 0 (i.e., DDO thinks there is no current record), it will clear the table's buffer so that the buffer matches what the DDO thinks is the current record. This should probably not happen with System files. DDOs should not be able to clear a system file's buffer.

This is an old behavior but rarely occurs. For this to happen you need a system file DDO; that file needs to be attached to the DDO structure and that system file DDO has to not yet be in use when it receives the Refind_Records message. None of these are normal or even common conditions.

Add_Focus changes the value of the hoParent parameter as if it were by-reference

Bug 7051, reported by Frank Cheng
If you send or forward-send Add_Focus to the runtime class level, your first parameter, which is hoParent, will get changed during the call. It will end up containing the Add_Focus return value, which most likely will be 0. If you use the Get syntax (for example Get msg_Add_Focus of hoButton hoParent to iRetVal), the return parameter (iRetVal) will be unchanged (because the return value is getting placed in the first parameter).

For example, in DF 18.1, open the Order Entry example, set a breakpoint in DFAbout.pkg (in the pkg folder) at line 477:

Procedure Add_Focus Integer hoParent
Forward Send Add_Focus hoParent // <<<<< Set a breakpoint on this line

Send Delete_Data // <<<<< Set a breakpoint on this line as well

End_Procedure

Notice the value of hoParent: it should be something non-zero. After the forward send, hoParent becomes 0, which is the return value of a successful Add_Focus operation.

This has been in the product since Add_Focus was introduced. The problem is rarely encountered because:
1. Add_Focus is not called or augmented often,
2. you don't tend to use the hoParent parameter after the call, and
3. Add_Focus rarely fails so testing the return value is usually zero anyway.

Possible side effects from this fix: 1. You were depending on a send/get to Add_Focus actually changing the first parameter to a return status value. Since this is not intentional or documented behavior, this seems unlikely. 2. You are using the Get or Forward Get syntax like this: 

Forward Get msg_Add_Focus hoParent to iRetVal
If (iRetVal) Begin
  // handle the add_focus failure
End
Because iRetVal was not actually receiving the return value, it was 0 (or whatever it was) even if the Add_Focus failed. Now that it might be called, your code is working as documented but may be untested. Keep in mind that Add_Focus rarely fails, so this code path will most likely remain unexecuted.

Orphan records can cause problems with multi-level relates-to constrained AutoFill DDOs

Bug 6953, reported by Garret Mott
When relates-to constrained DDO structures have child or grand-child records that are null-orphans, the finding process may not behave as expected. A null-orphan is a child that has a null relate (0 or "") to a parent. This is only an issue if the DDO is Auto_Fill, which usually occurs when a DEO Grid is connected to a child DDO (which sets the DDO Auto_Fill_State to True).

During parent finding and autofill, relates-to child attempts to find a related record. An empty parent will find the null-orphan child and consider it valid. With multi-level DDO constraints (parent <- child <- grandchild) where there is no child record, a null-orphan grandchild will find a valid record for the empty child.

This creates erratic behavior. In some cases, a parent clear will result in a grid of orphan "children". If the grandchild is the orphan a parent clear will cause the parent to appear cleared.

A multi-level constrained DDO structure might be: 

Customer
 \ c
 OrderHea
  \ c
  OrderDtl
Where c indicates a relates-to constraint. Orphans in OrderHea or OrderDtl can cause display problems.

The DDO constrained child find propagation behavior has been changed so that a null parent will always make sure that the child is null (i.e., it will never find and never accept a null-orphan).

This is a very old DDO behavior. This may result in changed behavior in a view, but in these cases that change should be an improvement. You should only see changes when you have constrained child null-orphan records (which is almost always an error in itself).

Form, dbForm and CJ column grid controls display some characters oddly when editing under Windows 10

Bug 6951, reported by Quality Assurance
Forms, dbForms and CJ grid column edits (which use Forms for editing) do not display heavily kerned characters well when editing them. Examples are FAFAFA or VAVAVA. Windows 10's Segoe UI kerns these pairs much more heavily than earlier versions. The logic used to determine character string width should have taken kerning into account but for some reason did not. The width is now determined using a different mechanism.

This is not Windows 10-only; you could see the same behavior with other fonts (e.g., Helvetica in Windows 7), but that is rare. Characters are displayed and stored properly — the issue only appears while editing the form.

StringToUCharArray has a memory leak

Bug 6942, reported by Harm Wibier
Each call to StringToUCharArray left behind a small amount of unclaimed memory.

Example: 

Use Windows.pkg

Procedure test String st
  UChar[] uca
  Move (StringToUCharArray(st)) to uca
End_Procedure

Repeat
  Send test "john"
Loop
Using the Windows memory monitor you can observe memory use slowly increase in 18.1 but not in 18.2.

Context menus in Forms and dbForms show Copy and Cut enabled when Password_State = True

Bug 6912, reported by John Tuohy
Setting Password_State in a Form or dbForm disables copy and cut, but the context menus allowed these options. They did nothing when Password_State is True, so this was cosmetic. The Can_Copy and Can_Cut functions were returning the wrong value and have been fixed.

StatusPanel does not work properly when used from a modal dialog

Bug 6843, reported by Quality Assurance
If StatusPanel is used from a modal dialog it did not stop the user from interacting with the dialog behind it, including closing it. This bug was introduced in VDF 12.0 when the improved modality logic was introduced and the status panel was replaced.

To reproduce: - Place the attached SL in the Order sample (replaces the standard Customer.sl) and add an extra button; example: 

Object oButton1 is a Button
  Set Location to 32 98
  Set Label to "Sentinel"

  Procedure OnClick
    Integer userCancel
    Send Initialize_StatusPanel of ghoStatusPanel "Cap" "Tit" "Msg"
    Send Start_StatusPanel of ghoStatusPanel
    For WindowIndex from 0 to 1000000
      Send Update_StatusPanel of ghoStatusPanel (Trim(WindowIndex))
      Get Check_StatusPanel of ghoStatusPanel to userCancel
      If userCancel Procedure_Return
    Loop
    Send Stop_StatusPanel of ghoStatusPanel
  End_Procedure
End_Object
- Run Order. - Bring up Customer view and press the prompt button on Customer Number — the modal dialog will be displayed. - Click on "Test StatusPanel" — the status panel will be displayed. - Click the Search button on the modal panel — the text displayed on the status panel will pause (no visual update) while the process continues — OK. - Click the Cancel button on the modal panel — the status panel may disappear from the screen while the application is still running the process (fixed).

FindByRowid / Find_By_Recnum may not set Found properly if the finding value is 0/Null

Bug 6826, reported by Raveen Ryan Sundram
In some cases, FindByRowId and/or Find_By_Recnum returned the global indicator FOUND as True even if the find was False. If the finding value is "no-record" (zero recnum or null RowId), the DD Clear message is sent. If this message changes Found, it may return True. This has been changed so these messages return the proper value for Found.

DataDictionary's IsDataInvalid function in a transaction would rollback the transaction if the data was invalid

Bug 6813, reported by Allan Kim Eriksen
The private DDO function IsDataInvalid was used to determine if the data being moved to the DDO buffer can be properly cast. It performed a cast and trapped errors via an error object. This had side-effects inside a transaction: testing for invalid data generated an error which rolled back the transaction and aborted the function. This is not intended behavior.

This function has been changed to evaluate without rolling back the transaction. It can now return True without aborting the transaction.

Forms and DbForms with Entry_State = False can still be changed via Delete and Backspace keys

Bug 6810, reported by Allan Kim Eriksen
If a (db)Form's Entry_State is False, you can place the cursor inside the form but not enter any data. However, Backspace, Delete, and the period key on the numeric keypad could change contents when they shouldn't. Context menus also provided options that should be disabled (e.g., Paste and Delete). These have been fixed.

UCharArrayToString raises an exception if end position < start position

Bug 6800, reported by Quality Assurance

Test code: 

Procedure OnClick
  UChar[] myString
  String sValue

  Move (Ascii("T")) to myString[0]
  Move (Ascii("e")) to myString[1]
  Move (Ascii("s")) to myString[2]
  Move (Ascii("t")) to myString[3]
  Move (Ascii("i")) to myString[4]
  Move (Ascii("n")) to myString[5]
  Move (Ascii("g")) to myString[6]

  Move (UCharArrayToString(myString, 2, 4)) to sValue
End_Procedure
Previously this could raise an exception if the end position was less than the start position. This has been corrected.

Operation_Mode and Operation_Origin are not reset when the transaction is aborted inside Request_Validate

Bug 6732, reported by Quality Assurance
Operation_Mode and Operation_Origin were not reset when a transaction was aborted inside Request_Validate. This only occurred with nested transactions (i.e., a DDO Request_Save inside a Begin_Transaction / End_Transaction block). The behavior is corrected.

To reproduce (example button code added to Customer.vw): 

Object oButton1 is a Button
  Set Location to 5 182
  Set Label to 'oButton1'

  Procedure OnClick
    Integer iRet
    // Begin_Transaction
    Send Clear of Customer_DD
    Set Field_Changed_Value of Customer_DD Field Customer.City to "ADAD"
    Get Request_Validate of Customer_DD to iRet
    If (iRet = 0) Send Request_Save of Customer_DD
    // End_Transaction
  End_Procedure
End_Object
If Begin_Transaction / End_Transaction were uncommented, Operation_Mode could be left in an incorrect state.

Variant and RowId return types in watches window give "External function not found" (e.g., pvXml, CurrentRowId)

Bug 6661, reported by Quality Assurance
Some object-based methods that returned variant or rowid types could not be evaluated in the debugger's watches window or via the Eval() function. Examples: pvXML(hoXML) or GetCurrentRowId(hoDD) returned "Error: External function not found". This has been fixed.

Reproduction steps (examples shown in original report) show adding watches to halted debug sessions resulted in the error.

Times are displayed incorrectly when using Mask_Time with European (Dutch) Windows Regional settings

Bug 6648, reported by Peter van Mil

Steps to reproduce: 1. Convert Customer table in Order (Windows, not Web) sample to SQL Server in Database Builder. 2. Click Refresh from definition for Customer. 3. Add column Test_Time, type time. 4. Drag the new column from DDO Explorer to Customer view. 5. In dbForm: 

Set Form_Datatype to Mask_Time
Set Form_Mask to "hh:mm"
6. Change Windows Regional Settings: set Format to "Dutch (Netherlands)". 7. Compile and run.

Results: - Entering 08:15 becomes 20:15 after save (database still has 08:15:00). - Times that are 00:00:00 in the database are shown as 12:00.

If you remove Form_Mask, the time is displayed correctly.

Problem with XML nodes longer than the maximum argument size (memory overwrite)

Bug 6636, reported by Emil Stojanov
XML documents that contain nodes longer than the maximum argument size could create a memory overwrite. For example, executing a Get psText might cause a memory overwrite instead of truncating. This was fixed in 18.0: when text is too long an error DFERR_STRING_TOO_LONG is raised. Messages affected: Get psText, psXml, psNodeValue, TransformNode, Value, and SubStringData.

AM/PM handling: datetime/time values with more digits than mask and AM/PM can be wrong

Bug 6615, reported by Quality Assurance
If the datetime or time value being set has more digits than the mask and it has AM/PM, the result can be wrong.

Example: 

Set Form_Datatype to Mask_Time
Set Form_Mask to "hh:mm ap"
Set Value to "4:01:00 PM"  // may become 4:01 AM

AM/PM vs 24-hour mask conversion problems

Bug 6614, reported by Quality Assurance
If Value is set with AM/PM while the form mask uses 24-hour time, conversion problems can occur.

Example: 

Set Form_Datatype to Mask_Time
Set Form_Mask to "hh:mm"
Move "16:17:18" to tt1
Set Value to tt1

Value set with AM/PM and Mask_Datetime_Window issues

Bug 6613, reported by Peter van Mil
If Value is set with AM/PM, time problems occur when used with 24-hour mask datatypes.

Example: 

Set Form_Datatype to Mask_Datetime_Window
Set Form_Mask to "mm/dd/yy hh:mm:ss"
Set Value to "1/2/2013 6:01 PM" // may become 6:01 AM
Set Value to "1/2/2013 12:01 AM" // may become 12:01 PM

24-hour masks that are not complete show an extra separator when editing

Bug 6611, reported by Peter van Mil
If the form_mask is "hh:mm", pressing End shows 09:15: (extra separator). You can't enter seconds unless you press Backspace first. This was fixed for dates but not time; behavior improved in 18.2. Ensure Windows "Long Time" Regional Settings set to 24-hour time when testing.

Example dbForm: 

Object oCustomer_TestTime is a dbForm
  Entry_Item Customer.TestTime
  Set Location to 84 62
  Set Size to 13 48
  Set Label to "TestTime:"
  Set Label_Justification_Mode to JMode_Right
  Set Label_Col_Offset to 2
  Set Form_Datatype to Mask_Time
  Set Form_Mask to "hh:mm"
End_Object

A Direct_Output within Read/Readln changes their behavior (SEQEOL is cleared)

Bug 6573, reported by Andrew Kennard
A Direct_Output executed during an input process resulted in SEQEOL being changed. SEQEOL is used by Read and Readln to determine end-of-line. Sequential output commands should not change SEQEOL. This is now fixed.

Refind_Records may not find all records in Child DDOs

Bug 6556, reported by Quality Assurance
In 17.0 a change was made to make Refind_Records find down as well as up the DDO structure; this did not always work. Example test (replace Print button code in Order.vw): 

Procedure OnClick
  // check file buffers in the debugger - should be filled
  Clear Customer
  Clear OrderHea
  Clear OrderDtl
  Clear SalesP
  Clear Vendor
  Clear Invt
  // check file buffers in the debugger - should be cleared
  Send Refind_Records of OrderHea_DD
  // check file buffers in the debugger - should be filled
End_Procedure
This behavior has been corrected.

Vertically resizing a list that uses anchors causes it to move in large jumps

Bug 1717, reported by Grant Harrington
Using anchors with objects based on the list class caused the vertical size of the lists to move in large "jumps" when resized. This was addressed by the addition of new grid and list classes in DataFlex 16.0.

Database Builder

Spelling error in wizard on "Primary key and Recnum table conversion rules" page

Bug 6991, reported by Quality Assurance
SQL Server Conversion Wizard displays "Primay" instead of "Primary". Fixed.

Installation

DataFlex 18.1 Personal and Eval editions trigger errors on Windows 10

Bug 6920, reported by Quality Assurance
Evaluation and Personal licenses for DataFlex 18.1 were not fully compatible with Windows 10 for debug/run of Windows projects (unhandled FLT_DIVIDE_BY_ZERO exception). This will be addressed in the next release.

When Client.cfg contains CONNECTIVITY=N and dfini.cfg includes 4096=ODBC_DRV, it results in a startup error

Bug 5946, reported by Quality Assurance
When installing a Client License with Client.cfg containing CONNECTIVITY=N and dfini.cfg including 4096=ODBC_DRV, a startup error occurred. The 18.2 client installation now installs different dfini.cfg files depending on the CONNECTIVITY setting in the client configuration.

Debugger

Error in the Watches Window may change the value of the ERR indicator

Bug 6929, reported by Frank Valcarcel
The Watches window may show the wrong value for Err if evaluating a watch entry generates an error (e.g., "invalid message"). The runtime Err flag could be set to True, potentially disrupting the application flow. This has been fixed.

Reproduce steps outline provided in original report (adding watches that generate invalid message errors).

Packages

DataDictionary's augmentation of FindByRowIdExNoAutofill is named wrong

Bug 7093, reported by Thomas Murphy
The augmentation in DataDict.pkg was incorrectly named FindByRowIdExAutofill instead of FindByRowIdExNoAutofill (missing the No), so the augmentation was not called. This prevented OnPreFind and OnPostFind from being invoked as part of WebApp request synchronization. The naming is corrected. Note: in 18.1 this would not have compiled because of Bug 7092.

HttpVerbAddrRequest and FindByRowIdExNoAutoFill are defined improperly in FMAC

Bug 7092, reported by Harm Wibier
Messages GET_FINDBYROWIDEXNOAUTOFILL and GET_HTTPVERBADDRREQUEST were defined with an improper format ("|CI0$0" instead of "|CI$0"). The improper format worked when sending the message but prevented creating functions with those names (making augmentation impossible). Definitions corrected.

Time value typed into a cDbCJGridColumn disappears when tabbing out of column

Bug 7086, reported by Quality Assurance
When entering a time value on a grid column set to Mask_Time, the value was blanked out upon tabbing out of the column. This was fixed.

Reproduce: - Modify Order.vw column to: 

Object oInvt_Description is a cDbCJGridColumn
  // Entry_Item Invt.Description
  Set piWidth to 213
  Set psCaption to "Description"
  Set peDataType to Mask_Time
End_Object
- Find an order, navigate to the description column, enter a time and press Tab — previously the value disappeared.

Error 52 when using MASK_TIME on Grid

Bug 7011, reported by Clive Richmond
When a column's data type is MASK_TIME and columns are sorted, clicking the column heading could trigger Error 52 ("Bad format of expression"). This occurred in sort comparison logic and has been fixed. Reproduction and stack trace provided in the original report.

In cDbCJGrids, saved records that are constraint-invalid are not removed from the cache and are displayed

Bug 6999, reported by Thomas Aravich
If a saved record becomes filtered (constraint or SQL filtering) and thus should not belong in the grid, it was not removed and could cause "can't refind record" errors. In 18.2 the record is validated post-save and, if it does not belong, it is removed from the grid (removed, not deleted). Note: saving a record and having it disappear may be confusing for end users.

Test steps and explanation provided in original report.

Prompt objects in modal dialogs do not work

Bug 6981, reported by Anders Ohrt
Prompt button logic for the DDO was disabled for the drill-down style by checking peViewStyle but only checking wvsDesktop; prompt buttons were also disabled for modal dialogs with peViewStyle = wvsDialog. This has been corrected.

If a DEO is not bound to a File.Field, changing this DEO sets parent DDO Changed_State to True

Bug 6974, reported by Ola Eldoy
If a DEO is not bound (Entry_Item missing or empty) and that DEO is edited, the change incorrectly set Changed_State on all parent DDOs (a change introduced in 17.0). As of 18.2, only the DEO's Server DDO will have its Changed_State set to True (restoring compatibility).

Header/Detail: changing data in header, navigating to detail DEO and saving may not save the header change

Bug 6973, reported by Pieter van Dieren
In a header/detail view, saving from the child DEO could result in the header value not being saved when the header DDO was treated as foreign (a side-effect introduced in 18.1). This is fixed. Note it only occurred when header is main DDO and it lacks Set Allow_Foreign_New_Save_State to True.

Reproduction steps provided in the original report.

Wrong function used in DDCurrentValue in cInternetSessionBusinessProcess.pkg

Bug 6971, reported by Torben Lund
On line ~400: 

Move (StringToUCharArray(UCData)) to sValue
should be: 
Move (UCharArrayToString(UCData)) to sValue
Fixed.

AddSoapHeaderNode uses wrong namespace with SOAP 1.2 services

Bug 6962, reported by Evertjan Dondergoor
AddSoapHeaderNode used SOAP 1.1 namespace: 

http://schemas.xmlsoap.org/soap/envelope/
for SOAP 1.2 services. It should use: 
http://www.w3.org/2003/05/soap-envelope
This has been corrected.

Client RPC web-services may not properly parse return values

Bug 6954, reported by Vincent Oorsprong
RPC web-services did not handle return parameter validation correctly and could return: 

Soap/Http Transfer error. Received SOAP data not formatted according to service description
This has been fixed.

Unhandled error when editing text field data in legacy ASP-style web application

Bug 6921, reported by Quality Assurance
Viewing and then saving a record containing one or more TEXT fields could cause an unhandled error. Fixed.

ParentNoSwitchIfCommitted allows parent to be switched if grandparent is committed

Bug 6905, reported by Wil van Antwerpen
Switching a committed parent raised an error, but switching a committed grandparent did not. This was introduced in 17.0 with committed record support and has been fixed.

Example hierarchy: 

Customer
|
OrderHea
|
OrderDtl
If OrderHea is saved and the Customer is switched then saving from OrderDtl should raise an error (now corrected). Reproduction example and UI suggestions provided in the original report.

Saving an empty text field via a dbTextEdit saves a zero byte string length 1 to the database

Bug 6897, reported by Quality Assurance
If you change a text field via a cDbTextEdit to empty text, the value saved to the DB will be a zero-byte string of length 1. Retrieving that data via Get_Field_Data returns a string of size 1 containing a 0 byte. dbTextEdit behavior changed and this has been fixed.

Field_Current_Value returns null-terminated string when retrieving a blank text field

Bug 6896, reported by Pieter van Dieren
Field_Current_Value on a blank TEXT field returned a null-terminated string (new in 18.1). This broke concatenation workflows (e.g., building merged strings). Fixed. Test example and reproduction steps are included in the original report.

Incorrect epoch conversion for years in 100–199 range

Bug 6824, reported by Quality Assurance
Dates between years 100 and 199 (e.g., 3/3/0145) were converted by adding 1900 (e.g., 1/2/123 → 1/2/2023). This ancient epoch fixup has been corrected.

Reproduce: 

Date dTest
Move 1/2/123 to dTest
Showln dTest

Wrap_State not shown in Properties panel for dbSpinForm and SpinForm

Bug 6805, reported by Lee Roden
Wrap_State was missing from the Studio Properties panel. Documentation mismatch between help and SpnFrmMx.pkg (default values) was fixed.

View_Latch_State does not work with local relationships

Bug 6793, reported by Raveen Ryan Sundram
View_Latch_State failed when a DD used local relationships because initial seeding used global file relates instead of local relates. This was corrected. Test steps and reproduction provided in original report.

SuggestionForm does not respect pbEnterKeyAsTabKey

Bug 6785, reported by Pieter Saelens
If pbEnterKeyAsTabKey is set in cApplication and you use a c(DB)SuggestionForm, the Enter key did not navigate to the next control. Fixed.

Combo Forms in cCJGrids flash and disappear instead of properly dropping down

Bug 6776, reported by Quality Assurance
Under specific conditions (manually changing Enabled_State while the grid's combo-edit has focus and pbComboEntryState = False) the combo would flash and disappear. Fixed. Contacts sample showed the issue.

cClientWebServer does not handle a simple element type with attributes when nullable simple types are enabled

Bug 6763, reported by Marco Kuipers
When nullable simple types were enabled (studio generates tNString instead of String) and used with simpleContent schema types (a simple value plus attributes), the generated struct had the null flag as the first member and the element value as the second; attributes followed. cClientWebService did not handle this; fixed.

OpenFileDialog returns OEM filenames but ANSI filenames if MultiSelect is true

Bug 6759, reported by Quality Assurance
Show_Dialog in AbstractFileDialog did not convert multiple filenames (when MultiSelect_State is True) from ANSI to OEM. Files in Selected_Files are now consistent.

Error dialog shows "VDF Error#:" instead of "DataFlex Error#:" or "DF Error#:"

Bug 6737, reported by Quality Assurance
The error dialog caption was incorrect. Fixed.

cHtmlHelp and a few classes should only be in the Windows (not common) class set

Bug 6727, reported by Quality Assurance
Help incorrectly showed cHtmlHelp as part of the common class set; it should only be in Windows class set. Same for: - cCJGridCachedDataSource - cCJGridDataSource - cDbCJGridDataSource - cCJGridDataSourceColumn

Mouse Up changes selected row in Grid (selection on both mouse down and mouse up)

Bug 6606, reported by Quality Assurance
CJ grid selection occurred on both mousedown and mouseup; previous behavior was mousedown only. Fixed so selection occurs consistently.

Transaction rollback leaves DEO Object_Validation set to True

Bug 6579, reported by Quality Assurance
If Request_Validate is called within a transaction and it raises an error, the DEO Object_Validation property was not reset. The runtime now resets this during error handling.

Reproduction and attached test view in original report.

SeedData does not find data in cCJGridPromptList if list not sorted first

Bug 6555, reported by Allan Kim Eriksen
OnSeedList assumed the data list was already sorted. If un-sorted, seeded find could stop early. Example: 

Object oSelList is a cCJGridPromptList
  Set Size to 111 291
  Set Location to 0 0
  Set peAnchors to anAll

  Object oCJGridColumn1 is a cCJGridColumn
    Set piWidth to 100
    Set psCaption to "column"
  End_Object

  Procedure Activating
    Forward Send Activating
    Send DoFillList
  End_Procedure

  Procedure DoFillList
    tDataSourceRow[] lsData
    // Note this list is not in order!
    Move "B" to lsData[0].sValue[0]
    Move "A" to lsData[1].sValue[0]
    Move "C" to lsData[2].sValue[0]
    Send InitializeData lsData
  End_Procedure
End_Object
In 18.2 OnSeedData detects unsorted lists and sorts them before searching. Workarounds and augmentation tips provided in original report.

Under some circumstances, mixin class properties are not displayed in Studio's Properties panel

Bug 6024, reported by Ian Smith
Studio did not show initial values for properties defined in immediate mixin classes in some views. This is fixed. Examples and steps in original report.

Help

Class Reference: some inherited properties, events and methods do not display in subclass lists

Bug 7066, reported by Quality Assurance
Examples:
- cWebGrid: Server
- dbTrackBar: Visible_Tick_State
- AboutDialog: Auto_Locate_State
Help listings updated to include inherited items properly.

Language Reference: Mod function has wrong example on negative values

Bug 6961, reported by Quality Assurance
Help stated:

Mod returns a value having the same sign as the quotient of {dividend} divided by {divisor} would have. Mod(3, -2) = -1

It should state:

Mod returns a value having the same sign as {dividend}. Mod(-3, 2) = -1

Documentation corrected.

Class Reference: Help samples for Notify_Select_State use incorrect parameter names

Bug 6868, reported by Chuck Atkinson
Help examples used ToItem, FromItem but the property panel prototypes use NewId, OldId. Parameter names have been made consistent in documentation and samples.

Class Reference: Document that Rebuild_Constraints does not clear DD buffer if row loaded is invalid

Bug 6566, reported by Emil Stojanov
Help updated to describe expected behavior when rebuild_constraints makes the current loaded row in the DD invalid.

Duplicate index entry for cDbCJGrid causing error

Bug 6383, reported by Flavio da Costa Figueiredo
Help index displayed both cDbCJGrid and cDBCJGrid. Clicking the second produced an error dialog. Index corrected to eliminate duplicates.

Class Reference: psText from BaseXMLDomNode doc incorrect (tags vs values)

Bug 4983, reported by Frank Valcarcel
Help previously said psText returns textual representation including tags and markups, but it actually returned values of nodes and descendants (no tags). Documentation updated to reflect actual behavior.

OnConstrain doc for cWinReport2 and BasicReport is blank

Bug 3953, reported by Samuel Pizarro
Documentation filled in for OnConstrain.

Studio Wizards

"Learn more about main DDO selection" button displays an error

Bug 7052, reported by Quality Assurance
In both report wizards the "Learn more about main DDO selection" button on the "Select Main DDO" wizard page showed an unsupported error. Fixed.

Migration Wizard: Images on pre-12.0 Workspace Migration Wizard are old-style

Bug 6958, reported by Quality Assurance
Pre-12.0 Workspace Migration Wizard still used old Visual DataFlex logo. Updated.

Pressing Esc in a wizard preview causes loss of all wizard data/actions

Bug 6923, reported by Jack Baugh
Pressing Esc while previewing a wizard previously cancelled the wizard and wiped out all selections. Behavior changed so Esc now acts like the preview window close (red "X"). If destructive action would occur, a warning is shown first.

Migration Wizard: pre-12.0 migration wizard creates .SWS file with wrong version information

Bug 6899, reported by Quality Assurance
8.0 to 11.0 migration wizard created .SWS files with Version property set to 17.1 instead of 18.1. Fixed.

Help does not work (F1 in Wizards)

Cannot reread all records in view during SyncDDO

Bug 6941, reported by Michael Salzlechner
pbOverrideStateOnShow = True optimized view loading but could result in SyncDDO errors on subsequent loads because view state wasn't rebuilt. Now the framework stores view definitions and rebuilds web objects to reset view state when needed.

Input filter may prevent valid characters from being entered

Bug 6940, reported by Eddy Kleinjan
Date/datetime input filters were too restrictive when editing parts of a date (e.g., 12//2015 then inserting a digit). The filter is now less strict and allows necessary edits while preventing invalid formats (e.g., too many separators).

WebSet and WebGet should throw compiler errors when called with an invalid object

Bug 6877, reported by Quality Assurance
WebSet/WebGet did not generate compile-time errors for unknown object symbols (unlike Set/Get). Compiler now catches invalid object names.

pbNewLine of cWebColumn_Mixin did not change when set at runtime

Bug 6851, reported by Thomas Murphy
No setter implemented for pbNewLine so runtime changes caused rendering issues. Setter added.

pbShowHeader of cWebList causes JavaScript errors when changed at runtime

Bug 6850, reported by Thomas Murphy
Changing pbShowHeader with WebSetResponsive could hide header but not show it again; JS errors occurred. Logic updated so header visibility toggles safely across sizes.

Reproduction steps included in original report.

Ctrl+End in cWebPromptList does not show data

Bug 6838, reported by Quality Assurance
Ctrl+End immediately after opening a cWebModalDialog with a cWebPromptList could wipe out list data; page-up or arrow-up restored data. Fixed.

The Should_Save Web DEO message does not work and should be removed

Bug 6736, reported by Quality Assurance
Should_Save on web DEO classes raised an error and should not be used. Use Should_Save of the DEO's Server or IsViewChanged of cWebView instead. Should_Save will be removed from web DEO classes and documentation.
