pageflow and facelet emails problem

[phant]

I've a pageflow with a start-page as shwon below

   <start-page name="anagraficaDatiGenerali" view-id="/facelets/ins_anag_generale.xhtml">
      <redirect/>
      <transition name="gotoDatiIndirizzi" to="checkDatiGenerali"/>
      <transition name="gotoLuogoNascita" to="selectLuogoNascita"/>
   </start-page>

From action a send an email using renderer.render
           

renderer.render("/facelets/email/plain.xhtml");

But I receive the error shown below

08:29:55,421 ERROR [SeamPhaseListener] uncaught exception
java.lang.IllegalStateException: pageflow is not currently at a <page> or <start-page> node (note that pageflows that begin during the RENDER_RESPONSE phase should use <start-page> instead of <start-state>)
        at org.jboss.seam.pageflow.Pageflow.getPage(Pageflow.java:227)
        at org.jboss.seam.faces.FacesManager.prepareBackswitch(FacesManager.java:239)

        at org.jboss.seam.jsf.SeamPhaseListener.afterServletPhase(SeamPhaseListener.java:230)

I have no idea how to resolve the problem, may you help me?

We need much more information.

What calls this action? What request throws the exception? Where is the rest of the stack trace?

What happens if you comment out the line that renders the email?

Below you find the stacktrace, page.xml and xxx.jpdl.xml

The scenario is

1. I call the url http://.../facelets/insanaggenerale.seam and the page associated appears without errors


2. I click on commandButton (code is shown below)

<h:commandButton value="Test email" id="test" action="gotoDatiIndirizzi" type="submit" />

1. The code associated to gotoDatiIndirizzi is

public boolean isValid(){
renderer.render("/facelets/plain.xhtml");
return true;
}

The error appears (full stacktrace below)
