Er, Wil's post has nothing to do with Graham's problem. Wil ran into issues fighting Core Data's built-in undo registration and decided the best approach to manually record undo information himself instead. I am almost 100% certain Wil didn't then proceed to chuck out NSUndoManager. He just turned off Core Data's use of it. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
