Using isMemberOfClass with a tree of subclass of NSManagedObject

Hi all,

I've a CoreData base with some kind of object what are a subclass of an abstract class called "root" (root is a subclass of NSManagedObject). In a part of my code I need to catch all operation on object what are a child of root. For do that I use the notification NSManagedObjectContextObjectsDidChangeNotification and I would use "isMemberOfClass" method for test each objet. I don't know why but this method always return "NO" even of an object what are a chlid of root...

	Do you have an idea ?

Bests regards,
Yoann.
