Passing parameters between portletized ADF Faces applications, possible?

Question

Hello,
In the developer guide, section 4.5.3 (http://download-east.oracle.com/docs/cd/B32110_01/webcenter.1013/b31074/jpsdg_pages.htm#CHDGGCGE) it says that you can synchronize portlets using an ADF Faces component value. However, that example do not use a value coming from a real portlet, the parameter come from a selectOneChoice define in the container page.
Is there a way to achieve the same thing but with the selectOneChoice being placed in the WSRP 2.0 portlet? Basically the communication scheme is WSRP 2.0 to WSRP 2.0 which is something possible using URL parameters. However, the problem with JSF components is that they pass their values through a JavaScript launched POST submit so the values are never added to the URL and even worst, you cannot be sure of the generated parameter name as it depends on the context in which the component exists (mainly the presence of a parent NamingContainer) and the only way to know that parameter name for sure is to have a way to call component.getClientId(facesContext) which is impossible for the portlet container and therefore for the other portlets.
To put it shortly, is there a way to send a navigation parameter from a portletized ADF Faces application to its container page beside using goButton and goLink (we need to keep the action/actionListener functionality)?

Can someone explain how to assign a value to a parameter in JSF like in the ParameterFormPortlet source code? Something in replacement of this :
    if (viewMode)
      // Set the new parameter values. These will be intepreted by the
      // container as navigational parameters as the names match the names of
      // the declared parameters.
      actionResponse.setRenderParameter(PARAMETER1, param1);
      actionResponse.setRenderParameter(PARAMETER2, param2);
      actionResponse.setRenderParameter(PARAMETER3, param3);
    }I mean, how to replace setRenderParameter to achieve the same thing inside a JSF binding bean for example. Is it possible via the PortletContext?
Thanks in advance for any hint.
