Unable to bind portlet parameter with page parameter in webcenter portal

Question

Hi All,
I am trying to bind portlet parameter with the page parameter so that I can ahieve some business requirements.
Here is what I did,
In my Portlet producer application:
1) Created standards based portlet (jsr 286) with view.jspx and edit.jspx with rest of the things being default.
2) In my portlet.xml created two parameters and assigned these parameters to the portlet created above.
3) In the view.jspx added couple of output label adf components in the page.
4) deployed this to integrated weblogic server.
In my WC portal application:
Created a new page and added the portlet to this page( WSRP connection already exists).
deployed portal application on integrated server.
In the edit mode of the page I added one page parameter(Param1) and some default (constant) value added.
What I want is this:
when Param1 value is One display first output label and
when Param1 value is Two display second output label.
I am using jdev 11.1.1.5.0 with integrated weblogic server.

There is no need to use page parameters for this.
You also have two types of parameters depending on what you want...
1) Preferences: these parameters can be used on a user based level. This means that users can personalize the portlets. When a user change the value of a preference, it is only applied for that specific user
2) Public parameters: these parameters are used to customize the portlet. The value you set in these parameter apply for all users.
I have made a simple example to show these two differences: http://www.yonaweb.be/PortletTest.zip
The portlet has 4 inputText on it. The first two can be set by specifying One or Two into the preference.
The other 2 inputText uses the value of the public parameter.
You should only deploy the portlet and consume it in a webcenter application. In the webcenter application, you don't need to do anything special. All is done in the portlet.
I am guessing you don't have written the code that will get the value of the parameter:
in case of a preference you will get the value by following code:
   PortletRequest request = (PortletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
   PortletPreferences preferences = request.getPreferences();
   return preferences.getValue("outputparam", "One");In case of a public parameter (for customization instead of personalization) you use following code to retreive the value of a public parameter:
PortletRequest req = (PortletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
  String param = (String)req.getParameter("PublicParam");
  if(param == null)
      return "Three";
  return param;This code can also be found in the sample portlet application.
