Thank you Rick for your response. I will check again to make sure we have bi-directional relation. We see this issue only when the parent entity has been saved before the FK entity is saved. I will confirm the bi-directional relation.
Is there a way to plug in an external cache regardless of the issue? best, Alice -- View this message in context: http://openjpa.208410.n2.nabble.com/Issue-with-OpenJPA-default-cache-use-external-cache-tp7586064p7586073.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
