I agree that if what he’s doing is changing values in the dictionary then he’s not going to get a change notification for the dictionary. I just read his message again and I can’t read it as saying anything else than the entire dictionary is being replaced, perhaps it’s just how I read it. I think we need some clarification here about what’s really getting changed. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
