Changing Portlet header text dynamically

Question

I trying to change the Portlet header text depending on the value of a selected page parameter. e.g. I selected the FTSE 100 stocks link on a page and I want the portlet to display the list of stocks and the banner to say "FTSE 100" similarly if I pick the NASDAQ link I want the same portlet to list the NASDAQ stocks and the banner to say "NASDAQ". I have the stocks changing using dynamic pages and page parameters but I can't seem to get at the portlet banner title variable. I working on the latest portal release.

Hi Lisa,
It just so happens that the "Portlet Wizard" in JDeveloper creates the default edit view to modify the page title. Here is the code it created:
<pre>
// Get the PortletRenderRequest and Writer
PortletRenderRequest pr = (PortletRenderRequest)request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
PrintWriter out = pr.getWriter();
// Display a greeting
String userName = pr.getUser().getName();
out.println("<p>Hello " + userName + ".</p>");
out.println("<p>This is the <b><i>Edit</b></i> render mode!</p>");
// Customize the portlet title
String actionParam = PortletRendererUtil.getEditFormParameter(pr);
String action = request.getParameter(actionParam);
String title = pr.getParameter("filebrowse_title");
NameValuePersonalizationObject data = null;
try
data = (NameValuePersonalizationObject)PortletRendererUtil.getEditData(pr);
catch(AccessControlException ae)
throw new ServletException(ae);
catch(PortletNotFoundException pnfe)
throw new ServletException(pnfe);
// Cancel automatically redirects to the page, so
// will only recieve OK or APPLY
if (action != null)
data.setPortletTitle(title);
try
PortletRendererUtil.submitEditData(pr, data);
catch(AccessControlException ae)
throw new ServletException(ae);
return;
// Otherwise just render the form
title = data.getPortletTitle();
out.println("<table border='0'><td width='20%'>");
out.println("<p align='right'>Title:</p></td><td width='80%'>");
out.println("<input type='TEXT' name='filebrowse_title' value='" + title + "'>");
out.println("</td></table>");
</pre>
I hope this helps!!!
