    Description

      First, you can look through next jsp codes:

      <s:iterator status="stat" value="destObjects">
      <tr>
      <s:iterator value="visibleColumns">
      <td>
      <s:property value="destObjects[%

      {#stat.index}].%{fieldDefName}" />
      </td>
      </s:iterator>
      </tr>
      </s:iterator>

      Variable "destObejcts" is a <LIST> type which contains a serial of objects named "destObject".

      Variable "visibleColumns" is also a LIST of objects named "visibleColumn", and "fieldDefName" is a property of "visibleColumn".

      And thus value of expression "visibleColumn.fieldDefName" will be a property name of object "destObject".

      Above relationship between two objects sounds a bit boring. As a trouble, I failed to get the correct values of these dynamic fields of "destObejct", and I had tried in many ways, and next Struts2 expressions ALL could not work:

      <s:property value="destObjects[%{#stat.index}

      ].%

      {fieldDefName}" />
      <s:property value="%{destObjectsstat.index.%{fieldDefName}}" />
      <s:property value="%{fieldDefName}

      " />
      OR
      <s:iterator value="destObjects" id="do">
      <s:iterator value="visibleColumns" id="vc">
      <s:property value="#do.%

      {vc.fieldDefName}

      "/>
      </s:iterator>
      </s:iterator>

      However, if I specify a real fieldname out of the second iterator tag, it does work:
      <s:property value="destObjects[%

      {#stat.index}

      ].field1" />
