-isTemporaryID is implemented in NSManagedObjectID, not NSManagedObject. I presume that your NMTopicMapViewMO inherits from NSManagedObject.
If you can't find any place in your code where you might be sending -isTemporaryID to a NMTopicMapViewMO, then of course it might be that when the managed object ID goes away, it gets replaced in memory by a NMTopicMapViewMO. You could do the MallocScribble thing, but time would probably be better spent looking at your code. Or look further down in that call stack to see how this started. Do any of those Apple methods mention anything about a relationship delete rule being fulfilled? _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
