try this: | t.begin(); | //queues an update from stale uNode | //Node mergedNode = em.merge(fromNode); | | //refresh reads back queued model | em.refresh(fromNode); | | t.commit(); | i commented out the call to merge (i think this is the call that's undoing your changes) and changed the argument to refresh (now it's fromNode instead of mergedNode).
