PrimeFaces Push 5.0 with Wildfly 8.1 not working - jsf-2

Question

I'm planning to start using PrimeFaces Push coming with PrimeFaces 5.0.
I've tried to run the same example found here http://www.primefaces.org/showcase/push/notify.xhtml using Wildfly 8.1 but I can't receive any push message from backend bean.
Here is what I've on wildfly console :
01:50:34,926 INFO [org.atmosphere.cpr.AtmosphereFramework] (Thread-261) Latest version of Atmosphere's JavaScript Client 2.2.2

Here is my web.xml configuration for PrimeFaces push:
<context-param>
<param-name>primefaces.PUSH_SERVER_URL</param-name>
<param-value>http://127.0.0.1:8080</param-value>
</context-param>

<async-supported>true</async-supported>
</servlet>
<servlet-mapping>
<servlet-name>Push Servlet</servlet-name>
<url-pattern>/primepush/*</url-pattern>
</servlet-mapping>
I appreciate your help to solve this issue.

Answer 1

I had the same problem using Primefaces 5.0 and Atmosphere Runtime 2.2.0.
Solved it, by changing to Atmosphere 2.1.7 (which is still the newest version according to log output). Now push messages work fine...
