Cannot use non-POJO Hibernate entities with Seam-managed Session
----------------------------------------------------------------

                 Key: JBSEAM-2418
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-2418
             Project: JBoss Seam
          Issue Type: Bug
    Affects Versions: 2.0.0.GA
         Environment: WinXP, JBoss4.2
            Reporter: Dave Sunerton-Burl


When trying to use the Map-based mode of a Hibernate session, I get the error below. First, here's the code that causes the error...

final Session session = (Session) Component.getInstance("dynamicSession");
final Session mapSession = session.getSession(EntityMode.MAP);
final Map record = (Map) mapSession.get("TestEntity", 10001l);

...the last line causes...

"dynamicSession" is declared in components.xml as...

<persistence:managed-hibernate-session auto-create="true" name="dynamicSession"/>

The error seems to be connected to the HibernateSecurityInterceptor, which tries to get hold of a real class from the mapping (which doesn't exist - this is a non-POJO mapping). My workaround involved replacing the "org.jboss.seam.persistence.HibernateSessionFactory" with my own implementation which didn't add the interceptor (I will have to do without declarative security on the dynamic entities).
