Tranformation of a session�s parameter

["yunzapito@yunzapito.com" <yu...@yunzapito.com>]

  I have installed Cocoon 2.2.1 and tomcat 4.1.27 running under jdk1.4.
I´ve got a question about what should i do to transform a XML parameter
that I´ve obtained from an action and that I´m trying to tranform.


  <map:match pattern="acceso">
   <map:act type="session" /> 
   <map:act type="login">
      <map:generate type="session-attr" src="XMLActionResult"/>
   </map:act>
  <map:transform src="sesion/doLogin.xsl">
      <map:parameter name="contextPath" value="{request:contextPath}" /> 
  </map:transform>
  <map:serialize type="html"/> 
  </map:match>

I´m obtaining the next error message:
 org.apache.cocoon.ProcessingException: Failed to execute pipeline.:
java.lang.RuntimeException

The session-attr generator is the SessionAttributeGenerator. I suppose the
problem is that the generator produces DOM and the transformer needs SAX...


  could I make a transformation from DOM to SAX ?
  Where should I do it (I´m looking to the transformator code, but I don´t
know where and how to make the transformation from DOM to SAX) ?




   Thanks a lot.

I'll be that is a result of the bug I just posted to the list, regarding how 
SessionAttributeGenerator adds duplicate startDocument/endDocument SAX events 
to the pipeline if the object that is processes is a full DOM Document.  See 
my message about same....

Nope....pipeline processing is smart enough to take a DOM and stream it out 
as SAX events.  More likely the problem is the one I encountered.  Check the 
code fix I posted and try rebuilding Cocoon with the fix in place and see if 
that resolves your problem.
