portlet communication between JSF bridged portlets

hello folks,

first of all...iŽm pretty new to portlets so please be patient with me ;). iŽd like to build a small portal using the latest pluto-trunk and myfaces/jsf bridges. so far everything seems to be smooth but now iŽm at a point where i want to share data between portlets. example: user presses a logout button in one portlet and all other portlets change their content. how can i get a portlet to do something when i klick a submitbutton in an other portlet?

i guess i have to overwrite generic methods like doView() in my own class. this method is called, whenever a portlet refreshes, right? to achieve that i did the following:

public class LogonAction extends MyFacesGenericPortlet {
....          
public void doView(RenderRequest request, RenderResponse response)
 throws PortletException, IOException {
 super.doView(request, response);
}
}

unfortunately doView() is never called. is this the right way?

my portlet.xml for the portlet described above looks like this:

    <portlet>
        <portlet-name>LogonPortlet</portlet-name>			        
        <init-param>
            <name>ViewPage</name>
            <value>/WEB-INF/jsp/index_nolog.jsp</value>
        </init-param>        
        <init-param>
            <name>default-view</name>
            <value>/WEB-INF/jsp/index_nolog.jsp</value>
        </init-param>
        <init-param>
            <name>HelpPage</name>
            <value>/WEB-INF/jsp/help.jsp</value>
        </init-param>                
        <portlet-class>org.apache.portals.bridges.jsf.FacesPortlet</portlet-class>        
        <expiration-cache>-1</expiration-cache>        
        <supports>
            <mime-type>text/html</mime-type>
            <portlet-mode>VIEW</portlet-mode>
            <portlet-mode>HELP</portlet-mode>
        </supports>                
        <portlet-info>
            <title>login</title>
            <short-title>LogonPortlet</short-title>
            <keywords>LogonPortlet</keywords>
        </portlet-info>        
    </portlet>

and my web.xml:

  <context-param>
    <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
    <param-value>server</param-value>
  </context-param>

    <param-value>false</param-value>
  </context-param>  
  <context-param>

  <context-param>
    <param-name>org.apache.myfaces.AUTO_SCROLL</param-name>
    <param-value>false</param-value>
  </context-param>

  <filter>
    <filter-name>extensionsFilter</filter-name>

    <init-param>
      <param-name>uploadThresholdSize</param-name>
      <param-value>100k</param-value>
    </init-param>
  </filter>  
  <filter-mapping>
    <filter-name>extensionsFilter</filter-name>
    <url-pattern>/PlutoInvoker/LogonPortlet</url-pattern>
  </filter-mapping>  
  
  <listener>
    <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
  </listener>
  
  <servlet>
    <servlet-name>LogonPortlet</servlet-name>
    <servlet-class>org.apache.pluto.core.PortletServlet</servlet-class>  
    <init-param>
      <param-name>portlet-name</param-name>
      <param-value>LogonPortlet</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  
  <servlet-mapping>
    <servlet-name>LogonPortlet</servlet-name>
    <url-pattern>/PlutoInvoker/LogonPortlet</url-pattern>
  </servlet-mapping>    

any help to get me out of this mess is very much apprechiated. :)

regards,
nicolas
