So to work around it, I'm creating a mutable copy of the values dictionary, 
then setting my individual properties in the values dictionary, then 
setting the entire dictionary back using self.values = [NSDictionary 
dictionaryWithDictionary:mutableDict];

Does that seem reasonable?

I'd love to read the discussion on cocoa-dev if you have a link to that.

Thanks!

Brendan
