Tag use within another tag

["Oliphant, Geoff" <ge...@sealcorp.com.au>]

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

	<td valign="top">
		  <div align="right"><span class="content2">
		  <struts:ifAttributeExists name="proposedAccount"
scope="session">
		  <struts:iterate id="element" name="proposedAccount"
property="assets">
		  <struts:ifPropertyEquals name="element"
property="assetCode" value='<struts:htmlProperty name="asset"
property="assetCode"/>'>
		  <struts:htmlProperty name="element"
property="assetValue"/>
		  </struts:ifPropertyEquals>
		  </struts:iterate>
		  </struts:ifAttributeExists>
		  &nbsp;</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
