Core Data and Inheritance

Hi all,

I have a situation where I have a parent entity "Animal" and inheriting entities "Fish", "Mammal".
I need to be able to select the corresponding Fish from it's array controller by binding it with the selection from the Animal array controller.
The problem is the index counts for Animal and Fish won't be the same if a Mammal is added.

Is it possible to do this using bindings in interface builder?

Sorry if this isn't very clear.

Cheers,

Billy Flatman
