ChangeLog - MDriven Designer

June 2025

• 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 16729 (Modified on 2025-06-13): Modlr was confused order tagvalue creation - certain TV should force codegen, some should not - and if we assign the TV value prior to attaching it to owner modlr could not understand - order changed to first add, then set. Changing to defualt to WPF viewmodel editor since WebView requires a lot of prereqs WebClient right-click also updated selection wich made right-click action to target vSelected hard
• Revision 16728 (Modified on 2025-06-13): Problem that changes to ViewModel name did not invalidate RT model and thus failed When changing the name of the Span as it will need to redo the Type.ViewModels.<Names> type
• Revision 16725 (Modified on 2025-06-12): x
• Revision 16724 (Modified on 2025-06-11): Error check GetUsedMembersAndClassifiersAndVariables wrongfully tried to evaluate ShownBy-contextactions that will most likely use other context variables and thus fail - logic updated to avoid a wasted time. Problems on Actions in ViewModel tree - intermittent that they disappeared on Nestings, and on really large viewmodels they disappeared after first optout change - root cause discovered and fixed
• Revision 16723 (Modified on 2025-06-11): x
• Revision 16720 (Modified on 2025-06-10): ActionGroups on Vibed Vms
• Revision 16719 (Modified on 2025-06-10): New action under Extras/"Convert all viewmodels to actions default Opt-out", to help with large model move to use new action default Opt-out
• Revision 16718 (Modified on 2025-06-10): Adding setting on package DefaultOptOutActionsOnNewViewModels, that controls if new ViewModels should treat actions as default opt-out. This will not be used for AutoForms since it would defeat the purpose of AutoForms to quickly be able to navigate to other existing forms.
• 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 16715 (Modified on 2025-06-09): Designer 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 16714 (Modified on 2025-06-08): Vibe information - actions to created views are collected to menugroups The angular context menu for tables could show wrong set of actions due to bug regarding actions referenced from placed action column and opted out (ButtonOnly renderingposition) - this checking corrects the error from the 20th of may
• Revision 16712 (Modified on 2025-06-03): CHeckbox for requires root object we too wide in ViewModelEditor controls Paging buttons in web-ui(blazor/angular); when no results - "No results" is written where normally "0-50 of 1000" is written

Currently not implemented in WPF

March 2025

• Revision 16526 (Modified on 2025-03-31): New property on selfVM called DisplayMode - that has one of the values enum DisplayModeEnum { UINormal, UIModal, UIPopup,Technical, RestPost, RestGet, RestPatch, RestPut,RestDelete }; Since ViewModels may have multiple usages it is good to be able to know the current use
• Revision 16524 (Modified on 2025-03-27): Spans, ecopkg, and actions.actions xml files are now stored with a newline per attribute - to facilitate easier diff in git
• Revision 16518 (Modified on 2025-03-26): In ViewModelEditor tree - if PlacingContainer has Visible or Style expression - these now shows as subcolumns
• Revision 16512 (Modified on 2025-03-25): DeleteReasonSolveMethod may act on data and it was not enclosed in the delete transaction - it is now DynamicEnumString did not implement IComparable and if used in a orderby expression it then failed Minimum slider of ViewModel in WPF designer has been increased to 6400 pixels Modlr check if clipboard sometimes fails with com-exception and we did not catch all - fixed
• Revision 16498 (Modified on 2025-03-21): Modlr WebView2 reload safeguarded. In Turnkey we upgrade new keys when objects are saved with a special command - if your UI was only transients (or new unsaved objects) all keys are monitored for upgrade - and this logic failed when having nestings over a singlelink - then the replace of a singlelink value was mistaken as a key change - and this gave ripple effects further down the viewmodel graph - ending up as ghost rows in multilinks below the swap key point. Fixed
• Revision 16480 (Modified on 2025-03-20): Menu command AddSelectedIntoNewPC now works from outside the ViewModelTree
• Revision 16468 (Modified on 2025-03-18): DragDrop in ViewModel-web was impeded by initial space in html class info - its now more robust
• Revision 16467 (Modified on 2025-03-18): In the ViewModelEditor- the controls for advanced edit's background now has the same RightClickMenu as the ViewModel-tree , this will save you some dragging... In the ViewModelEditor- the controls for advanced edit for Column that ends in something classy but does not have an Associated nesting yet will enable a new button "Create Nesting" for people that work backwards
• Revision 16461 (Modified on 2025-03-17): BREAKING CHANGE: extra parameter added to https://wiki.mdriven.net/index.php?title=Documentation:OCLOperators_OnDelete OnDeleteReasonSolve(reason:string; checked:Collection(SysSuperClass)) method DirtyListServiceImpl could create deadlocks and has been rewritten to TryRetryLock, this lead to dirtylist maybe null and some updates to handle this Fixing WPF wecpof ReadOnly-symbol-updating
• Revision 16457 (Modified on 2025-03-14): Missed nullcheck in EnsurevCurrentIsWithinAndIfNotOrNullDoFirst could leave modal window empty - fixed LiveEdit timeout could give exception dialog - fixed

• 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 16445 (Modified on 2025-03-07): Codegen issues "ProjectItem.Kind" sometimes throws exceptions "Item not in collection" - we now ignore, CodeElement codeElement in ecoNameSpace.Children) // <- on class deletion this fails from time to time, "Syntax node is not within syntax tree" , trying again seems to work Better null check in some diagram actions

• Revision 16441 (Modified on 2025-03-05): Issues with WebView reworked - it now manages to restart after failure
