title: Symfony2 returning blank page after adding new route
body: <p>just started doing some symfony. The root URL i.e. /, works fine and the index/home page is returned well with all the contents. However, I just added a new route i.e. /contact, with it's required controller. When I try to get theis new contact page on a browser, I just get an empty page yet it returns a 200 response code, meaning the request was successful. Quite confusing for me. What could be the problem? Not much code for now since I got no logic but here's my controller:</p>
  
  <pre><code>class ContactController extends Controller
  {
      /**
       * @Route("/contact")
       * @Template()
       */
      public function contactAction()
      {
          return array(
                  // ...
              );    }
  
  }
  </code></pre>
