It is Bayeux as I said. which run in a différent servlet as the wicket one (or filter) on server side and an hidden iframe on the client side receives events trigerring javascript function. The communication between servlet and iframe is done via JSON. > > How i see it if possible is just an open channel > and over it flows the wicket ajax stuff (so the xml that wicket ajax > can parse) I think it is possible but need much more work that could be interresting. But with différents implementation for each server : tomcat != jetty != blueFish etc... So it needs a différent implmentation for each server : jettyCometServlet, tomcatJettyServlet, etc... and hopefully using the same client-side api. > > this way if something is triggered on the server the server can push > component rerender changes > to the clients who are displaying those components. If we writte ourself the *CometServlet we can image to write a client side wicket-comet.js allowing to wrap *CometServlet response in existing wicket-ajax. I think it could be fine ;)
