I have been thinking about this concept. Wouldn't it be a more elegant solution if I would use a custom regionRenderer, that renders a specific portlet if it finds a injectPortlet="MyPortletToInjectInstance" property in a region? But I don't know how to do this. What I found, is that the 1. DivRegionRenderer iterates through RegionRendererContext.getWindows() Of course this getWindows() function will not return a WindowRendererContext for the injected portlet since it is not configured via xml or the admin page. 2. For every WindowRendererContext it renders the window via RendererContext.render() So I assume I need to create a WindowRendererContext for every injected portlet too and call the RendererContext.render() with them. 3. JBoss implements whis WindowRendererContext with the WindowContext class. The constructor of this class is: WindowContext(java.lang.String id, java.lang.String regionName, java.lang.String order, WindowResult result) - What is the id? - regionname I can handle - what is the order? I think the above parameters can be easily created, but for the last parameter - WindowResult - I have no idea what to write. The constructor of WindowResult is: WindowResult(java.lang.String title, java.lang.String content, java.util.Map actions, java.util.Map windowProperties, java.util.List<org.w3c.dom.Element> headerContent, org.jboss.portal.WindowState windowState, org.jboss.portal.Mode mode) Can anyone help me on this?
