Fails with the same error as before. Since I'm in an NSArrayController
object is there anything special I need to do to create the object? I've
tried using the [self newObject] method as well as the one described before.

I completely understand. I guess what I'm looking for really is something
like a core/data/bindings best practices. When you want to say use more than
1 nib and propigate one or more selected objects across that boundary, what
types of patterns or best practices are there. I'd love to see something
akin to the new Quartz book that just came out. I'd buy that in a heart
beat.
Thanks,
Sean
