title: How to translate labels in Sonata Admin Bundle
body: <p>I'm using Symfony 2.3 with Sonata Admin Bundle.
  I know that I can translate a label in this way:</p>
  
  <pre><code>-&gt;add('shortDescription', null, array('label'=&gt;'shortDescriptionTranslated'))
  </code></pre>
  
  <p>But this is possible only with "configureFormFields" method, not for dataGrid and listFields.</p>
  
  <p>Can you provide me a complete example for translating labels in <em>global</em> way?
  I have looked here (<a href="https://stackoverflow.com/questions/15476707/labels-in-sonata-admin-bundle/15477170#15477170">Labels in Sonata Admin Bundle</a>) but I have no idea what to write in the xliff file.</p>
  
  <p>Thanks!</p>
