set value of a property as another property

[Michael Brown]

Hello to everyone!

I have a problem using struts2 custom tags.

I have a variable called data in my action class. data is an ArrayList of ArrayLists
Also, I have a variable called useIndex that says which element of every inner ArrayList will be send to java script function doSomething(element)

Now, I want to iterate through these ArrayLists:

<!-- I started creating table ...

<s:iterator value="data" status="status" id="row">
     <tr onclick="doSomething('<s:property value="#row[  HOW TO DINAMICALLY SET INDEX OF CURRENT ARRAYLIST???   ]" />' )">
                                <s:iterator>
                                    <td><s:property /></td>
                                </s:iterator>
     </tr>
</s:iterator>

I tried putting another <s:property value="useIndex" /> in it , something like this:

<s:property value="#row[ <s:property value="useIndex" /> ]" />

but it cannot be put there...

Does anyone has a solution to this problem?
Thanks.

Did you try %{useIndex}

Yes, I did, but it doesn't work...
