get the NSManagedObjectContext the document creates for you with [ super managedObjectContext ], get the store coordinator with [ managedObjectContext persistentStoreCoordinator ], create your own MOCs on that store, hold on to the MOC you have just created, ignore the one super created (or perhaps you can nil it, not sure) and then return it. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
