Seam reference 13.8 "Configuring Seam in a Portal" should: mention TransactionalSeamPortletPhaseListener instead of SeamExtendedManagedPersistencePortletPhaseListener.

Also, maybe it should give more details on what the etc is after portlet.xml, etc. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4006532#...
