      The same example works fine with JSF 1.2.But with JSF 2.0 i get the same exception for Seam 2.2.0 and 2.2.1

      Anyhow i get the seam variables resolved and application succeefuly deployed with JSF 2.0 but this error during page transition occurs. I use pageflow (jbpm-jpdl.jar) for stateful navigation.

      Any clues??

      My pageflow file reads like::

      <pageflow-definition xmlns="http://jboss.com/products/seam/pageflow"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation=
      "http://jboss.com/products/seam/pageflow http://jboss.com/products/seam/pageflow-2.2.xsd"
      name="hello">

      <start-page name="displayGuess" view-id="/hello.xhtml">
      <redirect/>
      <transition name="namaste" to="namaste"/>
      </start-page>

      <page name="namaste" view-id="/namaste.xhtml">
      <end-conversation/>
      <redirect/>
      <transition to="end"/>
      </page>

      <end-state name="end"/>
      </pageflow-definition>

      both the xhtml pages just have a helloworld printed in it!!
