title: View /page.jsf could not be restored
body: <p>I have problem which I cannot solve. When I refresh opened JSF page after the page is idle for example 10 minutes I get this error message:</p>
  
  <pre><code>serverError: class javax.faces.application.ViewExpiredException viewId:/page.jsf - View /page.jsf could not be restored.
  </code></pre>
  
  <p>How I can increase the JSF View time?</p>
