Re: Example of wicket atmosphere with channel
Emond, Sorry for my late reply. Just come back from holiday. I saw at contextAwareFilter and find it useful. But I have not tried it yet in my project. Currently I still depend on wicketstuff-push instead wicket-atmosphere. I was thinking to move to wicket-atmosphere because it is more easy to implement and has less code than wicketstuff-push.

I did not really implement channels, but made the changes that would allow you to implement channels. It is now possible to post an event to a single client (rather than all clients), either via the AtmosphereResource for that client, or its UUID. I also added a contextAwareFilter() to @Subscribe, which allows you to access the RequestCycle and session from the filter. This can be used to differentiate on the receiver of the event, where filter() can only be used to differentiate on the content of the event. Be careful with this new method though, because it will not scale very will with large numbers of concurrent users. Looking at the code again, I think I'm going to change the Predicate into a Function on AtmosphereResource. That would allow you to keep track of some attributes in AtmosphereRequest on which to write your filter, which puts a lot less weight on the server than setting up a RequestCycle.

Re: Example of wicket atmosphere with channel
I opened the link but unfortunately I couldn't view the source. It appears as internal error. Thank you for the link, I will download the example and run in my local instead.
