Well what have you got ... the Key. So you get the object from that. By storing the "related" object as a Key in your class you accepted the need to get it back yourself when you need it. I don't see how there can be any "automatic" way when you don't have a reference to the "related" object anywhere in your object; hence why JDO doesn't standardise any such process. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
