  <p>I've tried the following:</p>
  
  <pre><code>&lt;%=scoredDocument%&gt;
  &lt;s:push value="scoredDocument"/&gt;
  &lt;s:push value="#scoredDocument"/&gt;
  &lt;s:push value="%{scoredDocument}"/&gt;
  &lt;s:push value="${scoredDocument}"/&gt;
  &lt;s:push value="#page.scoredDocument"/&gt;
  &lt;s:push value="%{#page.scoredDocument}"/&gt;
  
  &lt;display:column title="Study Code" sortable="true"&gt;
      &lt;s:property value="id"/&gt;
  </code></pre>
  
  <p>The most frequent error is</p>
  
  <blockquote>
    <p>Caused by: tag 'push', field 'value': You must specify a value to push on the stack. Example: person - [unknown location]</p>
