Major Description
I have a CustomerInventory entity that has a reference to an Item entity. The cascade property for Item is set to ALL. I create a new CustomerInventory, and attach to it an Item that was previously found and detached (by closing the em). I add the CustomerInventory to an existing Customer, and merge in the updated Customer.
At commit time, OpenJPA tries to persist Item, leading to this exception:
<openjpa-2.0.0-SNAPSHOT-runknown fatal store error> org.apache.openjpa.persistence.RollbackException: Attempt to persist detached object "org.apache.openjpa.persistence.detachment.model.DMItem-org.apache.openjpa.persistence.detachment.model.DMItem-1225343083922". If this is a new instance, make sure any version and/or auto-generated primary key fields are null/default when persisting.
