How to pass request parameter to bounded task flow?

Question

Hi, this is probably a simple question, but just not sure how this should be done. I have a .jspx that contains an ADF region for a bounded task flow. The task flow has a required input parameter, e.g. objectId. I want to be able to pass a request parameter that's sent into the .jspx page to the task flow. For example, Test.jspx?id=123 should pass 123 for the objectId input parameter of the task flow.
When adding the ADF region to the page, the Edit Task Flow Binding dialog prompted for a value for the objectId input parameter. I wasn't sure what I can put for the value so I just hard-coded something like 123 for now. So in the page definition file, sometihng like the following got added:
    <taskFlow id="testtaskflow1"
              taskFlowId="/WEB-INF/taskflow/test/test-task-flow.xml#test-task-flow"
              activation="deferred"
              xmlns="http://xmlns.oracle.com/adf/controller/binding">
      <parameters>
        <parameter id="objectId" value="123"/>
      </parameters>
    </taskFlow>I'm wondering is there some EL expression I can use for the parameter value that gets the value of the id request parameter passed into the .jspx? Thanks.

you have to use it like.. #{bean.idValue} and in the getter of the id Value use it like
private int idValue;
//setter
//getter
public int getIdValue(){
          HttpServletRequest request =
            (HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
        int id = request.getParameter("id");
       return id;
}
