title: Symfomy2 get url parameter in routing condition
body: <p>I am trying to set up the following route</p>
  
  <pre><code>/**
   * @Route(
   *      "/api/list/{setName}/{order}",
   *      condition= "request.get('order') == 'something' "
   *
   * )
   */
  </code></pre>
  
  <p>but I can only produce 404s because the condition is never true although I pass in an order argument. I guess the "request.get('order')" part is wrong, but how to do it?</p>
