[jboss-user] [JBoss Portal] - sharing data between render() and processAction() method

I need to share data between the render() and the processAction() method.

The method of (my) choice (and I think the only? method) is using the PortletSession:

render() : 

  | request.getPortletSession("sharedData", value);


  | Object data  = request.getPortletSession("sharedData");
  | // do something with data

my question is now:

is there anything problematic about sharing data via the PortletSession?

I could think of problems because of the fact that the processAction and the render request  are seperate http requests. is there the possibilty that a 3rd render request comes between these two?

something like that
---------------------------------------<<<< REQUEST 3 ???
---------------------------------------<<<< portletX.render();
---------------------------------------<<<< portletY.render();
---------------------------------------<<<< portletZ.render();
REQUEST 2 (because of server redirect)

I would be very happy if someone could bring some light into this, although i'm not sure, if I made myself clear ... 

thanks in advance.
