When I package my project one of my widgets that has a list view does not show up. I have print strings checking the length of the list view items. This returns the correct number of things yet the actual entry text does not show up. This problem only occurs when running an executable. Works fine in editor, simulate, standalone game, etc.
Answer is ListViews are unusable in an executable. None of the built in events OnEntryInitialized, OnEntryGenerated, OnListItemObjectSet work in an executable.
