Calling SGridPanel::SetRowFill on an actor's BeginPlay causes the editor to crash with the callstack provided
The reporter mentioned SetRowFill uses if() statement where SetColumnFill uses while() statement - changing SetRowFill to SetColumnFill in repro steps does not cause a crash
Regression:
No - same behavior occurs in 4.16.3 (CL 3561208)
TSharedPtr<SGridPanel> GridPanel; SAssignNew(GridPanel, SGridPanel); GridPanel->SetRowFill(19, 10.0f);
Result:
Editor crashes when callstack
Expected:
Code is executed and PIE runs as expected
