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(); View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4194284#...
