We've noticed this problem as well. It only happens on Tomcat. I'm not sure
what is going on, but it all starts with Tomcat loosing query parameters on
the ws-request ("url/?0-1.IBehaviorListener.0-" is changed to "url"). This
makes it impossible for wicket to recognize the call to a behavior, causing a
redirect to a new page on the ws-request, which is not allowed.
The question is, is this a bug in Tomcat, Atmosphere or wicket-atmosphere. I
would say it's a bug in Atmosphere. I've created a ticket for this:
https://github.com/Atmosphere/atmosphere/issues/553
For now, using jetty is a work around.
Best regards,
Emond
