Nope. Welcome to the wonderful world of undo! Where despite the promise of the API, the framework **really** doesn't like it when you call -[NSUndoManager removeAllActionsForTarget:]. Your delete should be undoable, right? So undoing the delete will make your undo group meaningful again. I hope. That's how it works for us in our non-Core Data apps, anyway. Hopefully Core Data is smart enough to be able to associate undo groups with resurrected managed objects. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
