This project has pretty much nothing else in it but the UMG components in question, so it should be very clean.
I didn’t really do anything special to get the project into a state of crashing other than put together the few blueprints and UMG elements. The non-UMG blueprints should be browsable without crashing. And if you’re careful, you can see most of the UMG blueprints without crashing.
GTPlayerInfo struct: Text fields about a player, such as name.
GTGameMode: Holds the array of GTPlayerInfo
GTPlayerControllerBP - no additions
GTPlayerListRow - Won’t crash under inspection. Just a horizontal box with two child text boxes.
GTPlayerList - Won’t crash under inspection. Has a ListScroll with a single GTPlayerListRow to be used as a header for a list control with columns and a header.
The Graph has a Event Construct which initializes the header row with the column label text. It then iterates the array of GTPlayerInfo structs in GTGameMode, adding a new GTPlayerListRow for each.
GTPlayerMenu - Won’t crash if you open GTPlayerList first. Has a vertical box with a GTPlayerList and a Button in it. Crashes if you attempt to do anything with PlayerList widget.
I don’t feel I’m doing anything weird to bring about the crash anywhere. The only thing suspect would be the “Event Construct” iterating on the GTPlayerInfo array.
