One advice: some very subtle and hard-to-find @Persist-related bugs
may happen when you return "this" in a event handler method. Return
null instead.
Another advice: Session.load() raises an exception whan the wanted
object was not loaded in this session before. As stated before, use
Session.get().

This is a LazyInstantiationException. It happens when you try to
lazy-load some property value from an object that is not associated
with an open session. To associate an object with a session. do
session.lock(object, LockMode.NONE).

IMHO, it is a bug.
