> final Map record = (Map) mapSession.get("TestEntity", 10001l);
> ...the last line causes...

> 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).
