Spring Web-Flow and the Annotation Driven controllers do not have any special handling for the MINIMIZED WindowState. This means the default behavior is the portlets render normally whenever they are minimized. To address this a HandlerInterceptor to skip rendering when minimized. The handler interceptor to accomplish this is listed below along with the Spring Bean's configuration snippets for both WebFlow and Annotation Based Controllers
