Exception from RsIterator

[Info]

Hello Everybody! I am working through the week end.

---------------------------------------------------------------------------------
J2SE 1.4.2_04 + OJB 1.0 rc6 + Struts 1.1 + J2EE (just in classpath)
---------------------------------------------------------------------------------
I am geting a report query by:
           broker = PersistenceBrokerFactory.defaultPersistenceBroker();

           Criteria crit = new Criteria();
           ReportQueryByCriteria q = 
QueryFactory.newReportQuery(ThreadDto.class, crit);
           q.setAttributes(new String[]{"priority", "username"});
      
           Iterator it = broker.getReportQueryIteratorByQuery(q);
           while (it.hasNext()){
               it.next();......................
               .....................
           }

but from line:   while (it.hasNext()) get the following exception

org.apache.ojb.broker.accesslayer.RsIterator$ResourceClosedException: 
Resources no longer reachable, RsIterator will be automatic cleaned up 
on PB.close/.commitTransaction/.abortTransaction
   at 
org.apache.ojb.broker.accesslayer.RsIterator.getRsAndStmt(RsIterator.java:876)
   at 
org.apache.ojb.broker.accesslayer.RsIterator.hasNext(RsIterator.java:228)

I tried to use Query instead of report query, and let it returns a 
Colleciton, everything is fine.
Later, I still used Query, but ask it return a Iterator (by method: 
getIteratorByQuery()), I get the same exception as above. It looks like 
not caused by report query but by Iterator return.

Please give advice,

Thanks!
Wallace
