[jboss-user] [JBoss Seam] - Re: access the entityManager in a converter (seam 2 beta)

[xalperte]

Hi,
I'm ussing the Seam 1.2.1GA with the SeamEntityManager (http://wiki.jboss.org/wiki/Wiki.jsp?page=SeamEntityConverter), and I'm having the same problem, this is the exception:

        ... 284 more

I don't understand what happends and why it happens?

What can I do to solve the problem? can I apply any patch to my environment configuration (download something...)?

Thanks
Javi
