Assume that whenever the edit button is clicked on the portlet, the portlet has to be displayed in maximized mode. Here the user is not clicking on a portlet url but the standard edit button of the portlet window. since the maximize has to happen everytime, I thought of putting the code in the doEdit(...) method. I see that the ActionResponse has the method setWindowState() but not the RenderResponse. so my code should look something like protected void doEdit(RenderRequest request, RenderResponse response) throws PortletException, IOException { // ** put code to maximize the window. ** // Edit View logic goes here. facesRender(request, response); } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3978753#...
