title: Is it correct that Jersey does not support declarative hyperlinking in nested resources?
body: <pre><code>public class Widget {
      @Ref(resource=WidgetResource.class)
      URI url;
  
      ...
  
      public URI getUrl() {
          return url;
      }
  
      public Wonkle getWonkle() {
          return wonkle;
      }
  
  }
  
  public class Wonkle {
      @Ref(resource=WonkleResource.class)
      URI url;
  
      public URI getUrl() {
          return url;
      }
  
     ...
  }
  </code></pre>
  
  <p>The JSON representation of the the Wonkle type has a url attribute with an appropriate value. However, when the Wonkle is used as a nested attribute in the Widget type, its url attribute has a null value.</p>
  
  <p>Am I doing something incorrectly, or is this this just the way the LinkFilter works?</p>
  
  <p>Thanks!</p>
