Comparing Struts2 values with Tiles2 strings

Can someone please tell me if there is a way to do a comparison between a Struts2 value and a String read in from Tiles2?  I'll post the code as I think it should work below.  If I just display the tiles value, I see it, but the conditional statement doesn't seem to evaluate correctly...


1<s:property value="#pagedDataBean.sortedBy"/> 	<!-- This prints the proper value -->
2<tiles:getAsString name='fieldName' ignore='false'/> <!-- This also prints the proper value -->

<s:if test="%{#pagedDataBean.sortedBy == <tiles:useAttribute name='fieldName'/>}">
...
</s:if>

Brian Stewart

Thanks Antonio!

I had confused nesting jsp tags with nesting a jsp tag within html which is allowed...
<div class="sortDesc" onclick="document.sort.action='
<tiles:getAsString name='action' ignore='false'/>';
document.sort.submit();">

Your suggestion completely solved my problem.  I had no idea how to pull tiles attributes into other scopes which was the missing piece of the puzzle.

	<tiles:importAttribute name="fieldName" scope="request"/>
	<s:if test="%{#pagedDataBean.sortedBy == #request.fieldName}">
	...
	</s:if>

Thanks again, and let me say that I really appreciate the work that you guys have been doing on Tiles2.  It is an invaluable tool.

As usual, you cannot use a JSP tag inside another JSP tag, you have to
use it outside.
However, <tiles:useAttribute> exports an attribute as a scripting
variable, <tiles:importAttribute> exports an attribute in a context
(page, request, session, application) and I don't know if it can be
used in a comparison with a value got from a ValueStack (I don't know
Struts 2 as much as you).
