A little more info on my example too. This is an M-N relationship and I am attempting to do a bidirectional unowned relationship not in the same entity group. What I am noticing is that when persisting side a, I do see side b created, and I see the reference to side b added to the list of side a and I see side b without a's reference in the datastore viewer. The error seems to be when it is attempting to store side a's reference in side b's list. Is the fact that these are in different transactions affecting this behavior?
I've double checked all the obvious problems. Both side a and b have each other's reference marked as @Unowned. Side b has the mappedBy set to side a's name. Unidirectional doesn't have any issues in my example. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
