Crash with UWidgetSwitcher in designer

Development Programming & Scripting UI

There is essentially no error checking relating to the ActiveWidgetIndex property of UWidgetSwitcher.

If this is set in the widget blueprint designer to be a non-zero index and then child widgets are dragged in/out of the switcher so as to leave the index being greater than the number of children, the editor will crash.

Hello ,

After doing a bit of digging I found that this issue is a know issue (UE-19741) and that it has been resolved internally. This solution will be available in a later release of the engine. Thank you for your time and information.

Make it a great day
