    Bug In exception handling

      Hi,


      If I have an exception page this works fine.
      If I add a parameter to that page e.g.



      <?xml version="1.0" encoding="UTF-8"?>
<page xmlns="http://jboss.com/products/seam/pages"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://jboss.com/products/seam/pages http://jboss.com/products/seam/pages-2.0.xsd"
      login-required="true" conversation-required="false" >

        <param name="cshid" />

</page>




      The page displays fine if I invoke it directly but from handling an exception it blows up as below.  The Contexts.getPageContext() is null ?  This is jboss-seam-2.0.1.CR1.
