edit: code getting data:

 @override public mobjectid findresult(final mobjectid id, boolean islocked)  {      criteria c = getsession().createcriteria(test.class);      c.add(expression.eq("objectid", id));      if(islocked)     {        c.setlockmode("this", lockmode.upgrade);      }      test extension = (test) c.uniqueresult();      return (extension != null)       ? new mobjectid("/ontpotssipextnr=" + extension.getid())        : null;   }

most probably, 1 of properties of entity not return exact same value set hibernate after loading. have if statements null handling or in getter or setter?
