Chances are, you are not updating the property in a KVO-compliant way.
First, make sure you are doing things correctly, before kludging a
workaround.

See:
http://developer.apple.com/documentation/Cocoa/Conceptual/CocoaBindings/Conc
epts/Troubleshooting.html#//apple_ref/doc/uid/TP40002148-DontLinkElementID_6

And if you haven't read that whole document, you really really need to.

Write lots of experimental code, but read relevant docs *before* you ask
questions. Get AppKiDo <http://homepage.mac.com/aglee/downloads>. Not only
does it greatly simplify browsing the API, it also makes it easy to find
conceptual documentation.

Unfortunately, just about every Cocoa book on the market is sorely out of
date. Kochan's Objectice-C book, however, is a must-have must-read.
