This is more of a dojo related question but since struts and dojo combination
is relatively common I thought someone may be able to tell me what's going
on here.
The problem is that dojo.event.connect doesn't like the element that is
referred in a second .jsp
(namely the line:
dojo.event.connect(ListB, 'onChange', 'listBEvent');
does not work as ListB comes in from listb.jsp, that is referred from
lista.jsp) - subsequently the 'listB' never fires listBEvent.
Is there anything that I am missing here or something that I may have
overlooked?
Any help is greatly appreciated.

Here is my setup:
struts.xml:
<!DOCTYPE struts PUBLIC

<struts>
<constant name="struts.objectFactory" value="spring" />
<package name="default" extends="struts-default">

</action>
<action name="listBAction" class="defaultAction"

<result name="error">jsp/error.jsp</result>
</action>
<action name="listCAction" class="defaultAction"

<result name="success">jsp/listc.jsp</result>
<result name="error">jsp/error.jsp</result>
</action>
</package>
</struts>
lista.jsp:
<script>
function listAEvent(event) {
alert("listAEvent [" + event.target.name + "]");
dojo.event.topic.publish("listAEvent");
}
function listBEvent(event) {
alert("listBEvent [" + event.target.name + "]");
dojo.event.topic.publish("listBEvent");
}
function init()
{
var ListA = dojo.byId('ListA');
dojo.event.connect(ListA, 'onchange', 'listAEvent');
var ListB = dojo.byId('ListB');
dojo.event.connect(ListB, 'onChange', 'listBEvent');
}
dojo.addOnLoad(init);
</script>
