Hi Ken Do you think that observing lots of objects with lots of keypaths is a good idea anyway? Maybe I'm considering my first approch again, using only key-value coding inside the view and move the observing somewhere else ... What I like about your idea is the use of [NSValue valueWithNonretainedObject:object]; I didn't know that. I'm quite new to coocoa, but not to programming. Since the number of keypaths for each object is constant, I might decide using a custom bitmap object as the value part in the dictionary. That bitmap would indicate which keypath is being observed. Thanks a lot. Patrick _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
