<script type="text/javascript">
var form = document.forms[0];
if ((form) && (formIsDirty(form))) {
var a = confirm("There are unsaved changes. Do you want to
continue?");
if (!a) {
dojo.event.topic.publish("/cancelNavigation");
//HOW TO CANCEL NAVIGATION??
}
}
onbeforeunload = function(e) {
if (formIsDirty(document.forms[0])) {
e.returnValue = "There are unsaved changes.";
}
}
</script>
When calling topic "/cancelNavigation" the event paremeter is
undefined... Do you know any way to cancel navigation? I mean, cancel
rendering the served page.

Using dojo.addOnUnload(function) neither works. Besides that, I would
need sht like dojo.addOnBeforeUnload, but it does not exist.
I don´t think I should subscribe for an ajax-request-completion
event, but for the beforeunload one, don´t I?
Thanks.
Use the dojo.connect function to listen to an arbitrary event. See
the comments to this related post:

I don't use it myself. Just pointing you in the right direction.
Also, if the script is inline within your ajax response, see the
recently updated notes on Handling AJAX Responses here:
http://struts.apache.org/2.x/docs/ajax-tags.html
(its written for 2.1 but mostly applies)
I'd consider turning on separateScritpts as well.
