Hello,

I am trying to use a named query to specify rows to return from a table. I get an error that implies that the result set was returned, 1 row was read, then the resultset was closed. It apparently tries to read from the closed result set and sql server shoots off an exception. Any ideas how to fix this?


Mapping:
Code:
      <sql-query name="findEventsByGroup">
         <return alias="r" class="events.TsnEvent" />
         
         select r.*
         from tsn_event r
         where r.tsn_event_group_id = :groupId
         
      </sql-query>


Code that calls it:

Code:
   public List getEventsAgain(){
      
      Session session = HibernateUtil.getSessionFactory().getCurrentSession();
      session.beginTransaction();      
      
      Query q = session.getNamedQuery("events.TsnEvent.findEventsByGroup")
                      .setParameter("groupId", new Integer(1));
            
      List li = q.list();
      
      session.getTransaction().commit();
      
      return li;
   }


Error:
