title: JMSSerializer deserializing collection
body: <p>I have a problem with deserializing serialized collection of doctrine collections. Couldn't  find docs about that and any topics and I'm new with JMSSerializer. When I try deserialize with:</p>
  
  <pre><code>$collection = $serializer-&gt;deserialize($jsonData,'Doctrine\Common\Collections\ArrayCollection','json');
  </code></pre>
  
  <p>$collection is empty</p>
  
  <p>When I set to null instead of class name I have assoc array on result. Is there an elegant way to deserialize that json?</p>
  
  <p>EDIT:
  Sorry. Here is serialized collection:</p>
  
  <pre><code>[{"id":88,"name":"Poland","created_at":"2012-09-28T11:59:06+0000"},{"id":90,"name":"Great Britain","created_at":"2012-09-28T11:59:06+0000"}]
  </code></pre>
