Subject Re: javax.persistence.EntityListeners is never called

Sorry about muddying the waters. As I stated, that suggestion isn't related
to the current problem... it is a best practice. That property is busted
and you can fairly easily get into deadlocks.

I am still confused The reason @PostLoad isn't called is because your
snippets look good. Can I have you put together some sort of a recreatable
test? That will help speed up diagnosis.

Thanks,
Rick
