Yes, you right. Castor only loads a primary keys of related address objects
using left outer join.

Yes. With one restriction: you should call iterator.next() in the same
transaction where you load your person object. Otherwise you'll get an
exception "Transaction is closed", or something like that.

No, it's not necessary.
