The following is create by seam-gen:

    </exception>
    
    <exception class="org.jboss.seam.security.AuthorizationException">
        <redirect view-id="/error.xhtml">
            <message>You don't have permission to do this</message>
        </redirect>
    </exception>
    
    <exception class="org.jboss.seam.security.NotLoggedInException">
        <redirect view-id="/login.xhtml">

        </redirect>
    </exception>
    
    <exception class="javax.faces.application.ViewExpiredException">

        <redirect view-id="/error.xhtml">
            <message>Unexpected error, please try again</message>
        </redirect>
    </exception>
    
</pages>

Note that the exception tag in the last block:

    <exception>
        <redirect view-id="/error.xhtml">
            <message>Unexpected error, please try again</message>
        </redirect>
    </exception>

does not a class attribute.  Is this the final catch all config for any exceptions other than the ones that are configured above it?  Is it roughly equivalent to the following?

<exception class="java.lang.RuntimeException">
    <redirect view-id="/generalError.xhtml">
      <message>Unexpected failure</message>
    </redirect>
  </exception>

What if you put the last block at the beginning of the exception block set?  Does it matter what order it shows up in the pages.xml?
