What does R0043: Parent object does not exist mean in PowerBuilder?
The application referenced a parent object, commonly through This or Parent inside an event, at a point where that parent object has already been destroyed or was never fully instantiated.
The application referenced a parent object, commonly through This or Parent inside an event, at a point where that parent object has already been destroyed or was never fully instantiated.
Check the object's lifecycle: a common cause is code running in a Destroy event that still tries to reference a parent window or control that is already partway through being torn down.
