Wow. I can't believed I missed that. I guess that's what I get for
using auto-complete to hastily in XCode. Thanks.
Thanks Daniel.

Michael - I think you have to use the setValue:forKeyPath: method
if you're passing a path as the target.

Hello everyone,
I have a question about compound keypaths. I have a class
that has as its only member a NSMutableDictionary. In IB I bound
to it various text fields. So the key paths that I bound to it
are say properties.title or properties.name.
The problem is I have been trying to set up undo for edit in
this program. When I get notified for an undo the key path it
return is "properties.title". However, when I try to do:
[object setValue: newTitle forKey: keyPath];
I get an error saying that the object is not key value compliant
for the key path. So what function name was I implement for it to
be able to set compound keypaths such as properties.title.
Thanks.
