Selected Property and NSPredicate
I know how to use NSPredicate with relationships, but for some reason, when I do the same with the property being retrieved, I get:
Application terminated due to uncaught exception "NSInvalidArgumentException", reason: "keypath address.id not found ...", where address is the selected property.
The code looks like this:
[NSPredicate predicateWithFormat: @ "address.id == '% i'", id]
Can you use the extracted properties with NSPredicate?

Have you tried [NSPredicate predicateWithFormat: @ "address.id ==% @", [NSNumber numberWithInt: id]];
if you have an address as an object, @ "address ==% @", addressObject should suffice.
