Description	In some methods of interactive context global status of interactive object is obtained from myObjects without a check if the object is registered inside. Example of crash, cased by it: In AIS_ViewCube implementation (0028954) there is AIS_ViewCubeFlat not displayed in context, but there is an owner connected to it and listening selection. The place, where the crash happens if we call it for this owner: void AIS_InteractiveContext::AddOrRemoveSelected (const Handle(SelectMgr_EntityOwner)& theOwner, ... { ... const Handle(AIS_InteractiveObject) anObj = Handle(AIS_InteractiveObject)::DownCast (theOwner->Selectable()); ... Handle(AIS_GlobalStatus)& aStatus = myObjects.ChangeFind (anObj); ... }
