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).
