Subject: Problem to subscribe a topic when trying to subscribe from an ajax
 called page.

What am i trying to do?
	-I need to publish a topic (dojo.event.topic.publish) on the event onchange
of a select tag.

The workflow is:
	-First i access an action that prints index.jsp page.
	-Then from that index.jsp i have a link (ajax) that loads an action in a
div (id="myCalendarDiv")
	-This loads mycalendar.jsp in the div myCalendarDiv
	-In that page i have another ajax link that loads mycalendar_planner.jsp.
		This last page "mycalendar_planner.jsp" has a s:select tag.
		In the onchange event, it tries to publish a topic
"updateReportsListTopic".
		
		Now the problem:
			-If i susbscribe the topic in the first page "index.jsp" (the only page
that wasn't call by ajax), it works.
			-But if i try to subscribe the topic in the mycalendar_planner.jsp (it
doesn't works).
				The problem is that i need to subscribe the topic in this last page.

If somebody has any idea of what can be wrong, or how to solve, i would
really appreciate, cause i already tried everything, and searched all the
web without results.
Thanks in advance!!

Guillermo




I attached some code from 3 jsp files mentioned for reference:
	-the links <s:a>
	-the subscription method
	-the publish method





index.jsp


<s:head theme="ajax" debug="true" calendarcss="calendar-green" />
<script language="JavaScript" type="text/javascript" src="dojo.js"></script>
<script type="text/javascript">
    function updateReports() {
    	alert('hola');
    }
    dojo.event.topic.getTopic("updateReportsListTopic").subscribe(null,
"updateReports");
</script>


<s:url id="urlMyCalendar" action="MyCalendar.action" />
<s:a href="%{urlMyCalendar}" targets="myCalendarDiv" theme="ajax"
notifyTopics="/myCalendarDayTopic">
	My Calendar
</s:a>




mycalendar.jsp


<s:url id="urlPlanner" action="MyCalendar!planner.action"></s:url>
<s:a href="%{urlPlanner}" theme="ajax" targets="myCalendarMain"
executeScripts="true">
	 pic/button/planner_calendar.png 
</s:a>





mycalendar_planner.jsp


<s:head theme="ajax" debug="true" calendarcss="calendar-green" />
<script type="text/javascript">
    function updateReports() {
    	alert('hola');
    }
    dojo.event.topic.getTopic("updateReportsListTopic").subscribe(null,
"updateReports");
</script>


<s:url id="urlPlanner" action="MyCalendar!planner.action"></s:url>
<s:a id="anchorPlanner" href="%{urlPlanner}" theme="ajax"
targets="myCalendarMain"></s:a>
<s:select label="Month" name="calView.selectedMonth" list="calView.months"
onchange="dojo.event.topic.publish('updateReportsListTopic' );alert('j2'); "
/>
