UnsupportedOperationException with StatelessSession
---------------------------------------------------

                 Key: HHH-3482
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3482
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.3.0.GA
         Environment: Linux, Hsql
            Reporter: Adrien
         Attachments: timestampStateless.zip

When using a StatelessSession and saving a ManyToOne, we have an UnsupportedOperationException because of a call to getTimestamp() on the StatelessSession. May be the AbstractEntityPersister.isTransient() should always return null when dealing with a StatelessSession, since everything is transient in this case.

StatelessSession s = getSessions().openStatelessSession();
s.beginTransaction();
Person p = new Person( new Long(1), "steve", 123 );
s.insert(p);
Order o = new Order( new Long(1), p );
s.insert(o); // --> UnsupportedOperationException

You may see the joined test case.

I found a old post on the forum with the same problem : 
http://forum.hibernate.org/viewtopic.php?p=2304937&sid=03c689ec5b12eebd8b26efa350241e80

I hope this will help.
