That example was really helpfull, thanks Geoff.
My case was somewhat more trivial (just a line of js) and I'm using got5
jquery. The containing parent injects a reference to the cart-like component
and handles events from other sibling components by invoking doRefresh, which
triggers the client side to onRefresh:
public void doRefresh() {
log.debug("doRefresh");
ajaxResponseRenderer.addCallback(new JavaScriptCallback() {
@Override
public void run(JavaScriptSupport javascriptSupport) {
String url =
componentResources.createEventLink("refresh").toURI();
javascriptSupport.addScript(
String.format("$('#cartZone').tapestryZone('update',
{url : '%s'});", url));
}
});
}
public Object onRefresh() {
log.debug("onRefresh");
setup(); // prepare for render
return cartZone.getBody();
}
This works like a charm although I feel I'm boilerplating with this code. Any
suggestions for improvement welcome.

Subject: Re: component events bubbling down?
Here's a working example that solves it in the same way that you were trying
- with bubble up and call down...
http://jumpstart.doublenegative.com.au/jumpstart7/together/ajaxcomponentscrud/persons
...where Persons, which is the page, calls list.doChangeOfSelectedPerson() in
response to several bubbled-up events.
