Embedded problem

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


Is there anyone could help me? Thanks.

Posted by Davey Xu <ta...@hotmail.com>.

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

It does not work yet :(

Maybe it is a defect of Struts2 which should be improved in the future.

As a choice, it is a good way to mix some JSTL tag or JS scripts in. But 
that seems to be complicated and boring. 

Is there any other solutions for this kind of question in Struts2.0?

Try something like:

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

I do something very similar in one of my apps but
don't have access to the code right now :/
