Hey Ian. Sorry, I had left that off the example - I also use @Per...Cap... with the options you identified. However, I have solved it. It seems that I had a back-relationship with "mapped-by" and added a backlink, which I didn't need, but the big thing seems to be that when I was fetching these entities, I did not detach them. So I got my persistence manager to do something like... pm.setDetachAllOnCommit(true); tx.begin(); ... tx.commit(); (or whatever). it's the either individually detaching or bulk detaching that wasn't working. Somehow some internal state in the PM was being messed up by my passing around non-detached persistent entities between transactions. cheers, Christian -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
