title: Symfony Assetic - part_1 in url
body: <p>Okay so I've been searching all over for some input into this but haven't found anything to help directly (only mentions of this problem in relation to something else).</p>
  
  <p>Basically I'm having problems with the path assetic generates when looking for an assetic file versus what is actually generated.</p>
  
  <p>The path it's trying to load is: <strong>/js/admin_part_1.js</strong> whereas the file it is generating is simply <strong>/js/admin.js</strong></p>
  
  <p>I am dumping files with:</p>
  
  <p><code>php app/console assetic:dump --env=prod --no-debug</code></p>
  
  <p>Relevant portion of the config.yml:</p>
  
  <pre><code>assetic:
  debug:          "%kernel.debug%"
  use_controller: false
  filters:
      cssrewrite: ~
  assets:
      admin_js:
          inputs:
              - @UserBundle/Resources/js/admin-tools.js
          output: js/admin.js
  </code></pre>
  
  <p>Loading the javascript tag via:</p>
  
  <pre><code>{% javascripts '@admin_js' output='js/admin.js' %}
  &lt;script type="text/javascript" src="{{ asset_url }}"&gt;&lt;/script&gt;
  {% endjavascripts %}
  </code></pre>
  
  <p>My question is, where is this phantom _part_1 coming from and how can I tell it stop adding it in?</p>
