Why one way works, but not the other?

[Vernon Wu]

To illustrate the problem, I provide the following two parts of code/file sample.

In a JSP file, I have the followings:

<jsp:useBean
  id="agentHelper"
  class="com.xxx.web.client.AgentHelper"
  scope="session"
/>

<c:set value="${agentHelper.newMembers}" var="pageResults" />

        <c:forEach var="item" items="${pageResults.list}" >
                <tr>
                <td class="TableRowColor"><c:out value="${item.headline}" /></td>
                <td class="TableRowColor">              
                        <c:url value="search-by-id-action.do" var="viewItemURL">
                                <c:param name="id" value="${item.userId}"/>
                                </c:url>
                                <a href='<c:out value="${viewItemURL}"/>' 
onmouseover="img_on
('signout')" onmouseout="img_off('signout')">
                                <c:out value="${item.userId}" />
                        </a>
                        </td>
                <td class="TableRowColor"><c:out value="${item.age}"/></td>
                </tr>
        </c:forEach>

This page works fine. I use the other implementation method using MVC pattern instead 
for another page. In the 
controller, I have the followings:

                session.setAttribute("mbox", a.openMessageBox(0, 10));
        
The data is correct at this point. And in the following JSP file I have the followings:

<jsp:useBean
  id="mbox"
  class="com.xxx.web.client.model.Page"
  scope="session"
/>

  <c:forEach var="header" items="${mbox.list}" varStatus="status">
  <tr>
        <td>
      <input type="checkbox" name="checkbox" value="checkbox">
    </td>
    <td>&nbsp;</td>
    <td><c:out value="${header.from}"/></td>
    <td><c:out value="${header.subject}"/></td>
    <td>&nbsp;</td>
    
  </tr>
  </c:forEach>

The iteration is walked through, but no data is displayed. I don't understand why the 
second implemention doesn't 
display the data. Can anyone see a problem here/

Thanks,

Vernon
