| Good idea, I tried this, but setPrimitiveValue:forKey: does also register its change with the undo manager.

NSManagedObjectContext *moc = [self managedObjectContext]; [moc processPendingChanges]; [[moc undoManager] disableUndoRegistration];
[self setSomeAttribute:@"Some Value"];
[moc processPendingChanges]; [[moc undoManager] enableUndoRegistration];
Is there a way to achieve the desired behaviour?
