recently, i upgrate my portlets from portlet bridge v1.0CR1 to v2.0FINAL.
my portal is jboss-portal 2.7.2

when start jboss-as, all portlets were loaded successful, but every portlet info:

06:33:52,765 ERROR [STDERR] Apr 27, 2010 6:33:52 AM javax.portlet.faces.GenericFacesPortlet calculateBridgeClassName
INFO: Bridge class name is org.jboss.portletbridge.AjaxPortletBridge

another question is when i click logout button on jboss portal, errors:

06:40:05,578 ERROR [[/myportal/elmPortlet]] Session event listener threw exception
java.lang.IllegalStateException: Please end the HttpSession via org.jboss.seam.web.Session.instance().invalidate()
