Got back to this issue after a while. The SessionExtension objects allows me to hook on to a session and get notified of various events.
My question is different: Given a session, before commit, how can I query it to know what is going to happen at commit. My intention is to derive from that, a corresponding change to another table, for the purpose of audit trail.
