My implementation is very simple and less efficient than cometd. It's
actually the client which is polling the server at a regular interval. The
only advantage over a pure javascript solution is that it's pretty well
integrated with wicket, so that you don't have to worry much about the
implementation. I also plan to provide a cometd implementation, based on
your work in WCD. But I need time to work on that, and for the moment I have
other priorities. But I will create an issue with my push implementation
attached in a moment, so that you can see if it can be of any use for you.
Issue with patch here :
https://issues.apache.org/jira/browse/WICKET-363
It seems to work properly now on wicket-1.x branch, maybe the blocking bug
was fixed this week-end.
