title: Forcing page reload from Vaadin portlet
body: <p>Is there an easy way to force the entire page to reload from Vaadin? I have a portlet which affects the header value displayed which is pulled from IBM WebSphere's dynamic cache in a separate JSP. </p>
  
  <p>I am porting over an old JSF portlet to Vaadin which depending on page reloads between actions to reflect the new value in the header template. So now I need to force the entire page (not just the portlet) to reload to make it appear that the action took effect.</p>
