1) I think I need to implement validateValue: in my
model class to validate the value when it changes.
What I need to check is the "title" value inside the
properties mutable dictionary. However, I have tried
to do this but it never seems to get called. I have
tried:
- (BOOL)validateProperties:(id *)ioValue
forKeyPath:(NSString *)inKeyPath error:(NSError
**)outError


It's not clear why you're implementing this method -- or where.

See <http://developer.apple.com/documentation/Cocoa/Conceptual/ KeyValueCoding/Concepts/Validation.html>.
