I have an Entity Bean that uses a GUID generator for setting its PKs (rather
than a sequence). I have it working by setting the GUID in the constructor, but
I want to avoid that, so I tried writting a @PrePersist method (see below) that
sets my PK. Now, even though the docs say @PrePersist is called before a SQL
CREATE, JBoss (4.0.3RC1) is throwing an exception with the message "ids for
this class must be manually assigned before calling save()".
BTW, if I set the GUID in the constructor (which, again, I want to avoid) and
place some other stuff in the @PrePersist method, it does get called before the
DB INSERT happens.
Any clues? The method is presented below.

@PrePersist
public void prePersist () {
setGuid(Guid.generateGUID(this));
}
