title: href assetic doesn't work
body: <p>I'm trying to link the stylesheet to an html template, but it doesn't seem to work.</p>
  
  <p>I use symfony2 and assetic. In the demo bundle, the css is linked with the line:</p>
  
  <pre><code>&lt;link rel="stylesheet" href="{{ asset('bundles/acmedemo/css/demo.css') }}" /&gt;
  </code></pre>
  
  <p>So, in my mainBundle, I wrote the lines </p>
  
  <pre><code>&lt;head&gt;
  &lt;style&gt;  
    {% block stylesheets %}
      &lt;link href="{{ asset('bundles/acmemain/css/demo.css') }}" rel="stylesheet" /&gt;      
    {% endblock %}                               
  &lt;/style&gt;      
  &lt;/head&gt;
  </code></pre>
  
  <p>and put my demo.css file in the folder </p>
  
  <pre><code>Acme\MainBundle\Resources\public\css,
  </code></pre>
  
  <p>then I executed</p>
  
  <pre><code> php app/console assets:install
  </code></pre>
  
  <p>In this situation, my web page doesn't have css style, it is without formattation. If I write my css directly in my template, it works. But if I link it, it doesn't work. </p>
  
  <p>How can I solve this?</p>
  
  <p>My css file now is only a line:</p>
  
  <pre><code>h1{color:blue;text-align:center;}
  </code></pre>
  
  <p>Thank you.</p>
