Error description

• Environment:
  - Operating System: Microsoft Windows XP
    - Product name: Rational Business Developer 7.5.1.3
  Description of problem:
  NotSerializableException: egl.java.FacesContext
  
  This happens when using HTTP session replication in WebSphere
  Application Server and also when using render parameters
  together with request-scoped faces managed beans in EGL
  portlets.
  
  Step to reproduce:
  1. Enable HTTP Session Replication within WebSphere Application
  Server. Configure a data source where the HTTP sessions will be
  stored, Within Application Servers ? server1 ? Session
  management ? Distributed environment settings, click on the link
  Database, specify the JNDI name of the data source just created
  and enter the credentials
  2. Create an EGL Web project. Create a .jsp file index.jsp if
  necessary
  3. Edit the .jsp file, add a button button1, create a JSF action
  on the Quick Edit tab and add in the .jsp file source code for
  the tag hx:scriptCollector an attribute
  preRender='#{index._preRender}'.
  4. Edit the generated EGL file index.egl for the page so that it
  looks contains this
  ???
  handler index type JSFHandler {onConstructionFunction =
  onConstruction, onPrerenderFunction = onPrerender, view =
  'index.jsp', viewRootVar = viewRoot}
   viewRoot UIViewRoot;
  
   // Function Declarations
   function onConstruction()
   end
   function onPrerender()
    SysLib.writeStdout('onPrerender');
    if (J2EELib.getRequestAttr('var1') != null) //EXCEPTION IS
  HERE
        SysLib.writeStdout('var1=
  '+J2EELib.getRequestAttr('var1'));
    end
   end
   function button1Action()
    SysLib.writeStdout('click on submit');
   end
  end
  ???
  5. Run the page on the server and click the button
