Title: Tag use within another tag

Hi all,

I've got a jsp page that outputs a table of data from two beans. I use iterate tags to produce a row in the table for each record in an ArrayList in the first bean. So that works fine, I can output fields in the row from each field from the arraylist in the bean using <iterate> and <htmlProperty>.

The problem arises when I want to produce the last field in the row. That field comes from a similar array list in the second bean - only this field has to be based on the primary key of the object in the first bean so that the two match up. A demonstration will probably prove more helpful than words:

First code: no problem:

<struts:ifAttributeExists name="currentAccount" scope="session">
<struts:iterate id="asset" name="currentAccount" property="assets">
<td valign="top"><span class="content2"><struts:htmlProperty name="asset" property="assetCode"/></span></td>
<td valign="top"><span class="content2"><img src="images/shim.gif" width="1" height="1"><struts:htmlProperty name="asset" property="name"/></span></td>

        </td>
        <td valign="top">
        <div align="right"><span class="content2"><struts:htmlProperty name="asset" property="assetValue"/></span></div>

</td>

So within this first bean I need to get a value out of the second bean based on the first bean's value of AssetCode:

                <struts:htmlProperty name="element" property="assetValue"/>
                </struts:ifPropertyEquals>
                </struts:iterate>
                </struts:ifAttributeExists>
                 </span></div>
                </td>
        </tr>
        </struts:iterate>
</struts:ifAttributeExists>

The problem arises when the value attribute of the ifPropertyEquals tag. I need to output the assetValue ONLY if the assetCode matches the current iteration of the first bean.

I've looked at the archives to find similar problems and have tried everything - including changing the tld to allow realtime expression on value of ifPropertyEquals.

Any help is greatly appreciated.

Geoff
