Editor Utility Widgets Feedback

[Spoondog]

I’ve had this error a few times since starting to play with the editor utility widget - not sure if its to do with the widget or just a 4.22 UMG thing, and I don’t have a reliable repro yet but I’ll leave this here:

LogOutputDevice: Error: === Handled ensure: ===
LogOutputDevice: Error: Ensure condition failed: !IsGarbageCollecting() [File:D:\Build\++UE4\Sync\Engine\Source\Runtime\UMG\Private\Slate\SObjectWidget.cpp] [Line: 43]
LogOutputDevice: Error: SObjectWidget for 'Spoon_Tools_Rollout_C /Engine/Maps/Entry.Entry:Spoon_Tools_C_0.WidgetTree_0.Spoon_Tools_Rollout' destroyed while collecting garbage. This can lead to multiple GCs being required to cleanup the object. Possible causes might be,
LogOutputDevice: Error: 1) ReleaseSlateResources not being implemented for the owner of this pointer.
LogOutputDevice: Error: 2) You may just be holding onto some slate pointers on an actor that don't get reset until the actor is Garbage Collected. You should avoid doing this, and instead reset those references when the actor is Destroyed.

I think I have a reliable repro for this now. If I change some values in my editor utility widget after starting the editor, then open my widget blueprint and compile, it will always give this error (like it’s having trouble destroying something while it’s open). My widget sets its own values on startup, so essentially the error will always happen on first compile.
