<s:set name="thisCountry" value="regionList(0).name" scope="page"/>
or maybe
<s:set name="thisCountry" value="regionList[0].name" scope="page"/>
At any rate, you need to use the 'value' attribute to specify the value :-)

I wondered what is the struts tag equivalent of this JSTL to retrieve
the first element from an arrayList:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"; %>
<c:set var="thisCountry" value="${regionList[0].countryCode}"
scope="page" />
<c:set var="lastCountry" value="${regionList[0].countryCode}"
scope="page" />
Where regionList is of type ArrayList<RegionBean>
Looking at the online guides I guessed at
<%@ taglib prefix="s" uri="/struts-tags"%>
<s:set id="thisCountry" name="regionList(0).name" scope="page"/>
or
<s:set id="lastCountry" name="regionList(%{0}).name" scope="page" />
But these don't seem to work.
I'm happy that regionList is in scope and not null because an iterator
like this works OK
<s:iterator value="regionList">
<tr>
<td>
<s:property value="countryCode"/>
</td>
<td>
<s:property value="regionName"/>
</td>
</tr>
</s:iterator>
(the JSTL code I'm converting inserts a spacer row in the table when
the countryCode changes, hence the need to initialise before starting
the iterator)
Apologies if I missed something obvious ;-)
