I have created a simple test with a Person->Car one-to-one
relationship. When the relationship is "related", therefore both
objects get created, everything works fine. However when I change to
"depends" and create only the Person object, create fails saying:
org.exolab.castor.jdo.ObjectModifiedException: Transaction aborted:
Object of type Person with identity 1 has been modified by a concurrent
transaction.
Thank you for any help!
