The Portlet API defined three window states: normal, minimized and maximized. The portlet implementation must decide what to render for each of these window states. Web Flow exposes the string value of the window state under portletWindowState via the request map on the external context.

requestContext.getExternalContext().getRequestMap().get("portletWindowState");
