Thanks Drew! I'm guessing that this is a fairly common situation that we
should put on the FAQ and perhaps even add as a feature of Seam.

I'd like to note, however, that you can do exactly what you described with
this bit of configuration:

<exception class="javax.faces.application.ViewExpiredException">
   <redirect view-id="#{org.jboss.seam.handledException.viewId}">
      <message severity="warn">Your session has timed out. You were
redirected to the current page with a new session.</message>
   </redirect>
</exception>
