I just installed omnifaces library (2.0) using maven dependency as described here.
But whenever I access application I got NullPointerException from CDI @SessionScoped bean called ViewScopeManager:

I checked ViewScopeManager bean source code and it seems that activeViewScopes variable is null at that point. It is initialized by method called postConstructSession annotated with @PostConstruct annotation. I set breakpoint in that method and it seems that it's never called.
I'm using wildfly 8.2.0.Final web server with weld 2.2.9.Final. I tried using omnifaces as dependency with scope runtime and provided (as Wildfly module) but error still is present.
Is it bug in Weld? When bean is accessed first time weld should call method annotated with @PostConstruct.
Please help me solve this issue, and sorry for my english:)
Edit: It seems CDI is working correctly only when OmniFaces is used as war module deployment. It is only way. Thank You for your help.
