Some listener are not called

I'm trying to register several hibernate listeners under JBoss 4.0.3 using EJB 3.

In my hibernate.cfg.xml I've defined:

Code:

<hibernate-configuration>
        <session-factory>
                <listener type="flush-entity" class="sirma.biz.TheFlushEntityListener"/>
                <listener type="load" class="sirma.biz.TheLoadListener"/>
                <listener type="save" class="sirma.biz.TheSaveListener"/>
                <listener type="delete" class="sirma.biz.TheDeleteListener"/>
                <listener type="dirty-check" class="sirma.biz.TheDirtyCheckListener"/>
                ...

where

Code:

          public class TheFlushEntityListener extends DefaultFlushEntityEventListener
          public class TheLoadListener extends DefaultLoadEventListener
          ...

JBoss instantiates all the configured listener classes at deploy-time. But it only calls the methods of the "load" listener. (The way I test this is via overriding all protected and public methods of the super classes and logging something before calling super.theMethod(...), but none of them is called, except for TheLoadListener.)

What might be the reason?

It seems currently listeners cannot be overridden in the JBoss EJB3 preview.
I wonder if it is planned for future implementation?

Yes this is planned. We've made the listener event system more flexible in H 3.1 to allow several listeners per event.
Note that EJB3 listeners implementation are not always the same as Hibernate core listener

Thank you for the reply.
I had a look at the org.hibernate.ejb.EventListenerConfigurator and how the extended ejb listeners are set.
Can you possibly say when event listeners could be used with ejb3 (I mean, the jboss implementation)?
