Hi Stefan,
Rather than making your javascript depend on understanding Tapestry’s workings,
perhaps you can simply command things from the server-side? When the
server-side responds to the request with a zone, eg.
ajaxResponseRenderer.addZone(zoneElld); could it also respond with a callback
commanding the listeners to refresh themselves? Eg.
ajaxResponseRenderer.addCallback(makeCallbackToRefreshListeners()).
If you need an example of this kind of callback, look in Modal.java in
