title: <h:link includeViewParams="true"> does not include URL parameters
body: <p>I have a JSF page which is opened by an URL like <code>test.xhtml?a=15&amp;b=20</code>.</p>
  
  <p>I have a link which should pass all URL parameters to the next page.</p>
  
  <pre><code>&lt;h:link outcome="index" includeViewParams="true" value="Include all url parameters" /&gt;
  </code></pre>
  
  <p>I was expecting that when I click on the link it will go to <code>index.xhtml?a=15&amp;b=20</code></p>
  
  <p>But I don't see anything in the URL. Did I understand the <code>includeViewParams</code> wrong?</p>
