In my HUD C++ class I made a
UFUNCTION(BlueprintNativeEvent) void OnMyWidgetClosed(); void OnMyWidgetClosed_Implementation();
Then in BP HUD class I tried to attach it to the Blueprint Event Dispatcher
But the blueprint fails to compile with this error:
Error Failed to create property K2Node_Event_OutputDelegate from Output Delegate due to a bad or unknown type (Delegate)
Binding a simple custom blueprint event compiles fine.
