On application start i will see the login page of our application. From this point each action that causes a server communication end with this error:

Everything works fine, when i remove the push parameter from the servlet configuration. Is there something wrong with my push configuration?
I just encountered this issue while developing a push-enabled app on TomEE as well:

Is there any way to somehow “re-connect” the WebBeans context to the current session?
It seems that this is really a problem in JavaEE spec. So, the solution seems to either use @UIScoped or disable Push and use long-polling, until JavaEE resolves this.
I have yet to see if the performance is altered in any way.
