title: How do I load this form theme from my App Bundle? (symfony)
body: <p>I have an app with the following directory structure in Symfony 2.6</p>
  
  <pre><code>src/
      App/
          MainBundle/
              Forms/
                  template.html.twig
  </code></pre>
  
  <p>And I'm trying to use this as a form theme along with the bootstrap3 theme. According to the documentation I can apply multiple themes. So I've updated <code>config.yml</code> to look like this:</p>
  
  <pre><code># Twig Configuration
  twig:
      form:
          resources: 
              - 'bootstrap_3_layout.html.twig'
              - 'AppMainBundle:Forms:template.html.twig'
  </code></pre>
  
  <p>However, when I add the second resource I only get a blank page. It must be something to do with the way I'm referencing the template -- I can reference another one of the built-in ones and it works correctly.</p>
  
  <p>Thanks.</p>
