What do you try to win by changing the attribute bind CD's back? If you want to take it out of undo you might switch it off temporarily (e.g. [undoManager disableUndoRegistration], or store the undo manager in a local, set the context's undo to nil, and restore it - which may or may not cause trouble depending on whats happening in your object graph. I use GCUndoManager to stay away from such trouble.)
Apart from that there is - (void)refreshObject:(NSManagedObject *)object mergeChanges:(BOOL)flag as well as the - (void)setPrimitiveValue:(id)value forKey:(NSString *)key methods, depending on what you intend to achieve. Dunno if these might help.
