George,
   Thanks for the reply.  I didn't realize that I would have to 
manually create the Address entity for a particular Person.  Anyway, 
I created the class files for Person and added code that creates an 
Address object and inserts it into the Managed Object Context then 
sets it's own Address relationship to point to the newly created 
object.  I bound the city text field to Person Arrray Controller with 
a key of selection and a path of "myAddress.city" and it all works. 
Thanks!
