I'm working on integrating Wicket with ICEpush, and have based my work off of the integration guide. The first time I deployed the application, I saw in the logs that while ICEpush caught on that there was asynch support, it wasn't properly enabled, and would fall back to the blocking thread. Here's a log snippet:2010-11-20 18:42:20 [http-8080-exec-2] DEBUG [org.icepush.PushContext] Created new pushId '1ggr0hh8m:3l8o'.

Everything worked properly - I clicked my Wicket button, and data was pushed down to the browser.


At this point, I decided to turn on async support, so I went looking in my web.xml and put in the necessary <async-supported>true</async-supported> block in the Wicket filter. The next time I loaded my page, I ran into some serious issues. For some reason, the connection was being terminated by the server side. Here is the log:
