title: Handle ViewExpiredException in the background and restore form values
body: <p>Is there a database-, primefaces- and "keep-session-alive"-free solution to prevent or to handle a ViewExpiredException silently in the background while restoring the form-inputs? </p>
  
  <p>for example a user with a "stay logged-in cookie" would prefer not to be redirected to some kind of an error- or start-page; he fills out some form values, comes back in an hour and then, when he submits the form, the same view is re-created with its previous inputs and the submit-action of the underlying requestscope-bean is re-executed again.</p>
  
  <p>i already took notice of omnifaces and mojarras </p>
  
  <pre><code>  &lt;o:enableRestorableView /&gt;
    &lt;f:view transient="true"&gt; 
  </code></pre>
  
  <p>but as we talk about permanent logged-in users, i am not shure, if this would be the right approach.</p>
  
  <p>thanks for pointing into the right direction.</p>
