Lifecycle events?

So, I’m trying to use the lifecycle events on the OpenJPAEntityManagerSPI.  I’ve created a class which implements PersistListener, UpdateListener, DeleteListener.  I’ve registered an instance of this class as a lifecycle listener:

OpenJPAEntityManagerSPI openJpaEm = em.unwrap(OpenJPAEntityManagerSPI.class);
openJpaEm.addLifecycleListener(this);

This does not seem to do anything at all.  I’ve got printlns in every event and I get nothing.  I have registered the txn listener successfully, and that works great.

Is there something I’m missing here?

Any help appreciated.

Thanks,

-Hal

no problem.  the work around works just fine.

Much appreciated ;)

Also, too, facepalm because I actually thought I’d tried this.

This is a bug. It will work if you specify a list of classes that you're
interested in or null. (You shouldn't have to pass null, but that is the
bug)

openJpaEm.addLifecycleListener(this, Class1.class, Class2.class);

or

openJpaEm.addLifecycleListener(this, null);

So, this is just a dead parrot?  I couldn't find anything through web searches. Can I get a read as to whether this is supposed to work or even a code sample?

Thanks.
