Vaadin 7.2.0 Push long polling not working with WildFly 8

Vaadin 6 / 7 / 8

Hi,

I´m using WildFly 8.1.0 CR2 Application Server and want to use the new long polling push.

But when using long polling I only get a loading indicator when starting my app and I´m not able to use the app.

Is only push over websockets supported for WildFly?

Thanks for your answers
