All the latest MDriven Fixes and Updates

ChangeLog - MDriven Framework

June 2025

• Revision 16737 (Modified on 2025-06-18): x
• Revision 16736 (Modified on 2025-06-18): Real life case where MDrivenServerSync-block was tagged with wrong ModelChecksum due to checksum from actual save block creation was not caught and kept - instead the checksum was retrieved again prior to insert of synkblock and at this point the evolve had added a new version. Freak occurrence blocked from happening again.
• Revision 16735 (Modified on 2025-06-17): When building ListViews - and having de-reference to single nesting (as will happen when mounting viewmodel) there is now support for IncludeHere tagged value that will NOT de-reference and put cursored controls out of listview as standard - instead IcnludeHere tag will bring in rendering into the current listview row; this makes it possible to have a list of mounted viewmodels (all the same definition though)
• Revision 16732 (Modified on 2025-06-16): When using ListViews the supported behavior has not allowed subnestings from row (worked only of subnesting was other listview) - for single links these where interpreted as "dereference/render-after" - but for MountedViewModel this made it impossible to have Mounts inside the ListViewRow , to better handle this the "IncludeHere" tag value can be set on the Mount-point-column or also on a SingleLink-reference; work in progress
• Revision 16731 (Modified on 2025-06-16): Mistake in SearchLogic from last checkin made TotalCount get value of pagecount if special search (missing words+semicolon) was tested but not applied - fixed
• Revision 16730 (Modified on 2025-06-13): Better return of checksum, null checks after real life scenarios TraceLogTurnkey now catches first trace with TRACESTART and prune app with PRUNEAPP trace entries to better see dynamics of usage
• Revision 16727 (Modified on 2025-06-12): Issue with ocleditor context finding when writing expressions - specially the case self.DeepClone(SomeType.ViewModels.SomeView) was not any good at any of the levels of the inner expression SomeType.ViewModels.SomeView
• Revision 16721 (Modified on 2025-06-10): Now Seekers in turnkey will init their vSeekerResultCount to -1 , and this will be used to avoid showing "No results" prior to first search The special search for missing words (replacing space with wildcard) has been limited to strings under 200 in length to avoid undue db stress The special search for multi-search had issues with AutoForms/Template created seeker forms due to use of vSeekParamWildcard that included wildcard in value to allow for sqlite to not having a parser meltdown... Long story, but fixed. Seekers-paging-buttons in web did not show count if the count was 1, it does now
• Revision 16717 (Modified on 2025-06-09): When parsing xml datablock we now fallback to check for Ansi-datetime on datetimes (before only binary) OCLDebugger has new button to Vibe demo data from a given diagram
• Revision 16716 (Modified on 2025-06-09): Runtime updated to allow for default-opt-out of actions making it easier to maintain large model where some viewModels should be stable and not get new class actions as they are added - but rather wait for explicit opt-in. This is a per viewmodel choice named default-opt-out
• Revision 16704 (Modified on 2025-06-01): Improved sorting on menus i web when mixing menus without group and those with group Continued work with Vibe-information

May 2025

• Revision 16693 (Modified on 2025-05-27): selfVM.ExecuteAction used internal function that could fail if Nestings for searchexpressions were present - fixed. Vibe UI - LLM updated prompt and fed xml to reduce misunderstandings
• Revision 16681 (Modified on 2025-05-25): Detection of issue with missing PlacingContainer in single Nestings when Span has them - this issue break rendering a new error in error check has been added - and also a rescue operation to fix with one click
• Revision 16680 (Modified on 2025-05-23): In C# Math.Round(-1.0/10000) gives negative zero that survives to ToString giving "-0.00". This is legit but annoying and deemed of low value so in MDriven (-1.0/10000).Round(2) will from now on return a positive zero
• Revision 16678 (Modified on 2025-05-21): Issue in ViewModelEditor with Mounted views - fixed
• Revision 16676 (Modified on 2025-05-21): Long limitation that Bag{1,2,3} did not really return a bag but instead a Set - combined with limitation that union filtered away duplicates gave this expression Bag{1,2,3}->union(Bag{1,2,3}) to return 1,2,3 instead of the expected 1,2,3,1,2,3 - fixed
• Revision 16670 (Modified on 2025-05-20): ActionRenderPosition has a new value:ButtonOnly, this is used when a leftside/toolbar action is opted out - but still used in one or more buttons This change fixes several old problems; specially the one that AreYouSureQuestions where not properly handled of action was outopted but used in button, and that optout level had importance for ViewModelContextAction
• Revision 16669 (Modified on 2025-05-19): DynamicEnumString did not correctly implement Equals leading to combobox presentation halting
• Revision 16668 (Modified on 2025-05-19): IgnoreContent of PlacingContainer implemented in WPF flexpanel
• Revision 16667 (Modified on 2025-05-16): ElementHandle did not correctly create columns when switching types if new type was IEnumerationType - effected debugger output that showed last result type if the result type was IEnumerationType
• Revision 16666 (Modified on 2025-05-16): Ocl_includes did not handle enum compare - fixed
• Revision 16663 (Modified on 2025-05-14): --text-on-primary text on buttons was set to white - but several issues made it not reach the theme-default, the theme-default issues has been resolved and then text on button became white - this is now changed to black Width of tk-input-field--datepicker was reduced - for no apparent reason - now its treated as any other input StylesInModel was unable to reach and set the text of buttons - now fixed Turnkey runtime prepared for new PlacingContainer property that controls flexbasis called IgnoreContent
• Revision 16659 (Modified on 2025-05-13): BREAKING CHANGE: Assignment := goes from RHS-type to LHS-type (Left hand side decides type today and onwards). This WILL MOST LIKELY break a few expression. You fix them by typecasting. Read how and why here: https://learn.mdriven.net/index.php?title=Documentation:OCLOperators_:%3D
• Revision 16658 (Modified on 2025-05-13): OclResultTypeDeduceMethod.TypeOfFirstParam was really 2 and OclResultTypeDeduceMethod.TypeOfSecondParam was really 3 - fixed this and also added OclResultTypeDeduceMethod.TypeOfThirdParam This gave problem when implict upgrading ints to double in a assign somedouble:=0 when it was enclosed in ->collect because the list was int and not of double
• Revision 16655 (Modified on 2025-05-13): ExecuteFrameworkRuntimeActionRT.ReadOnlyModeToogle is corrected to ExecuteFrameworkRuntimeActionRT.ReadOnlyModeToggle
• Revision 16641 (Modified on 2025-05-10): OclVariableConverter a TypeConverter needed for design and winforms design code gen has been moved from eco.handles.design to eco.handles - this is to de-confuse the winforms .net8 designhost (designtoolserver) and also de-confuse extension loaded types from project loaded types. This means that to get consistent behaviour (non missbehaving winforms editors) you need MDriven design time and MDriven nuget mdriven.handles no older than THIS version
• Revision 16640 (Modified on 2025-05-09): OclVariable as placeble component did not work with new required winforms net48<>net5 streaming - now works for net48
• Revision 16639 (Modified on 2025-05-09): OclVariable as placeble component did not work with new required winforms net48<>net5 streaming - work in progress
• Revision 16637 (Modified on 2025-05-09): ReadOnlyMode when turned on globally also affected MVCAutoForms - and that made debug editing harder - we now let these forms ignore ReadOnlyMode
• Revision 16636 (Modified on 2025-05-08): ReadOnlyMode when turned on globally also affected MVCAutoForms - and that made debug editing harder - we now let these forms ignore ReadOnlyMode SERIOUS BUG: A month old bug regarding IdentityChangers (new objects has guid id, and saved get permanent id) - when on root webclients did not correctly update url to show new id, and whats client side viewmodels did not get all the needed IdChange messages to correctly upgrade id on objects held deeper in hierarchy than root.

• Revision 16523 (Modified on 2025-03-27): RendersAction columns should take their ReadOnly state from the action-column they render, and this was not correctly implemented causing these columns to be enabled even when ReadOnlyMode was true. Actions in turnkey check again if they are enabled on the server just before execution to stop any injecting and outofsync execution Blazor checkboxes that render action should not also toggle their value - the action needs to be responsible for all data change Null check in client side VMClass Null check in debugger

• Revision 16451 (Modified on 2025-03-12): BREAKING CHANGE: in AfterModalOk in actions we no longer provide vModalResult_selfVM variable. It was an old mistake that that in WPF the handover of vDirties to instigating view did not happen correctly - so vModalResult_selfVM.save was sometimes used. The mistake/bug is removed and hand-over of dirties is now the same in Turnkey and WPF - but vModalResult_selfVM.save would then be moot - and to signal this change the vModalResult_selfVM variable was removed altogether from AfterModalOk. There were also issues in turnkey when handover sometimes caused nullref exceptions and breaking signaling
• Revision 16447 (Modified on 2025-03-07): Better handling of Tuple type re-occurence Null checks in VMClass SysGraphAPI error codes clarified in exception property (404-NotFound,403-NoAccess,401-NotLoggedIn)
