[jboss-user] [JBoss Portal] - Re: Custom navigation region

[JohnnyTheHun]

Ok, I don't get where the portlet markup get's created.

I see that the WindowContext already get's the markup via its String content parameter, so I need to create the portlet markup BEFORE instanciating a WindowContext

But how do I create the markup for a specific portlet instance?
What is the class that I can instanciate or the utility I can call to create the markup?

I looked at DivPortletRenderer which calls PortletRendererContext.getMarkup() to get the markup.

PortletRendererContext is implemented via PortletRendererContextImpl.
The getMarkup() function of PortletRendererContextImpl gets the markup from the WindowContext.

So now I'm in a circle - I have to create the markup before any XYContext comes into the picture. But I don't know what creates the markup for a Portlet instance.

The best would be to have some Class or Function like:

new PortletMarkupGenerator(String portletInstanceName).getMarkup();


I found some code in the injectTabbedNav of PageCustomizerInterceptor class:


  | public String injectTabbedNav(PageCommand rpc)
  |    {
  | ControllerContext controllerCtx = rpc.getControllerContext();
  |       ControllerRequestDispatcher rd = controllerCtx.getRequestDispatcher(targetContextPath, tabsPath);
  | 
  |       //
  |       if (rd != null)
  |       {
  |          Page page = rpc.getPage();
  |          PortalAuthorizationManager pam = portalAuthorizationManagerFactory.getManager();
  |          PortalNodeImpl node = new PortalNodeImpl(pam, page);
  | 
  |          //
  |          rd.setAttribute("org.jboss.portal.api.PORTAL_NODE", node);
  |          rd.setAttribute("org.jboss.portal.api.PORTAL_RUNTIME_CONTEXT", Navigation.getPortalRuntimeContext());
  | 
  |          //
  |          rd.include();
  |          return rd.getMarkup();
  |       }
  | return null;
  | }
  | 


The following lines are used to access the jsp to create the tabs:

  | ControllerContext controllerCtx = rpc.getControllerContext();
  |       ControllerRequestDispatcher rd = controllerCtx.getRequestDispatcher(targetContextPath, tabsPath);
  | 


1. This function renders a jsp file, it doesn't render a Portlet. 

2. This function uses a PageCommand instance to create the markup. But I don't see that a RegionRenderer gets a PageCommand parameter


So the best would still be to have some Class or Function like:

new PortletMarkupGenerator(String portletInstanceName).getMarkup();
