Hi,
I have a hiyerarchical entity tree and at some steps, this structure is cloned, but at some points the user may want to return to some previous state that was cloned before. The problem is that, non of the collections cascade MERGE (and must not) but I found no other way other than updating the top entity and cascading all merge operations to lower level entities whose status are all new since they are cloned and all have ID's null. Has anyone faced similar problems? Thanks in advance...
