I do lots of stuff -- in particular, sending notifications to implement business logic -- invoking other setters.

I have considered doing that but can't find any such examples right now. (Regarding my 'lastModified' attribute, my notification receiver tests for new != old.) _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
