[jboss-user] [JBoss Seam] - usage of @Transactional and em.joinTransaction ?

I see a lot of Seam code and examples that marks methods @Transactional and immediately do em.joinTransaction before using the em.  I was wondering what are the consequences of *not* following this pattern.  If I were using TransactionalSeamPhaseListener, there would always be a transaction active during a request, so what's the point of using @Transactional.  If I were using a seam-managed persistence context, doesn't it automatically do a em.joinTransaction()?  Correct me if I'm wrong.
