title: insert Enum value in param action
body: <p>I'm trying to set an Enum value to the Following action</p>
  
  <pre><code>&lt;action name="actionOne" class="SomeClass"&gt;
      &lt;param name="myValue"&gt;@some.package.Enum@VALUE&lt;/param&gt;
      &lt;result name="success"&gt;result.jsp&lt;/result&gt;
  &lt;/action&gt;
  </code></pre>
  
  <p>but when debugging it, it shows <strong>myValue</strong>:<pre>null</pre>.</p>
  
  <p>myValue corresponds to a private object with its public <strong>getter</strong> and <strong>setter</strong>.
  Is it possible to do this? what am i doing wrong?</p>
