title: Dozer mapping of Lists of Complex Object
body: <p>Is there a way to map one List of objects to one List of objects ids? 
  I have the following objects:</p>
  
  <pre><code>public class Role implements Serializable {
      private List&lt;Section&gt; sections;
      //getters and setters
      ...
  }
  
  public class Section {
      private Long id;
      //getters and setters
      ...
  }
  
  public class RoleDTO implements Serializable {
      private List&lt;Long&gt; sections;
      //getters and setters
      ...
  }
  </code></pre>
  
  <p>How can i map this with Dozer XML?</p>
