It's pretty much the same as any other operation on with a MOC. You cannot copy or move a managed object from one MOC to another in a simple fashion. Instead, you have got to create new, corresponding objects in the second MOC, and then (if needed) delete the old objects from the first MOC._______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
