title: How to redirect to the same page after a POST request
body: <p>How to redirect to the same page (I don't know the page; the redirection is done inside a menu shared by several pages) ?</p>
  
  <p>I tried</p>
  
  <pre><code>return "?faces-redirect=true";
  </code></pre>
  
  <p>at the end of the action method, but I received an error message because it is not possible to find a navigation case for "?faces-redirect=true".</p>
  
  <p>Thanks in advance for your help.</p>
