[jbossseam-issues] [JBoss JIRA] Updated: (JBSEAM-2418) Cannot use non-POJO Hibernate entities with Seam-managed Session

Dave Sunerton-Burl updated JBSEAM-2418:
---------------------------------------

    Attachment: HibernateTest.zip

I've attached a seam-gen generated project, with my additions, and NOT including the bootstrap or lib folders and their contents. You should be able to copy over these folders/contents and have a working project. There are a number of tests where I've been trying to narrow down what's going wrong here...

In the HibernateTests class there are 4 tests which just select both POJO-based and dynamic Map-based entities. They all pass. In HibernateConfigTests there's just one test which was going to test resetting the Hibernate configuration at runtime, but I've got stuck straight away. This test is just a copy of the checkManagedHibernateSession() in HibernateTests - BUT IT FAILS.

So, I'm stuck. One version of the test passes, the other fails. I've done a direct cut and paste, just in case. Until I can work out why this is happening I can't go on to test resetting the configuration. 

The HibernateSessionFactory implementation I've included will be used so that the Hibernate configuration can be changed at runtime (adding/removing dynamic entities) but commenting out the Seam annotations - so Seam picks up the inbuilt Hibernate SessionFactory gives the same results.

Any hints greatly appreciated!

> 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...

> 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).
