title: Unable to generate route
body: <p>I have a helper to get in the view what is my current route, but this line always return me a "NULL":</p>
  
  <p>I check with console route:debug and all routes are right. And my application works fine.</p>
  
  <pre><code>$currentRoute = $request-&gt;attributes-&gt;get('_route');
  </code></pre>
  
  <p>My helper works with other functions and I have Container injected.</p>
  
  <p>Any idea?
  Thanks.</p>
