WELD-001303 No active contexts for scope type javax.faces.view.ViewScoped

问题

I have switched to javax.enterprise.context.SessionScoped to javax.faces.view.ViewScoped Upgraded faces 2.1 to 2.2 to be able to use ViewScoped with my CDI injections.

After I switched to ViewScoped I have started getting this error and I can't figure out why! Do you think there is something wrong here?

Glassfish 3.1.2, Primefaces 3.4.2, JSF 2.2

org.jboss.weld.context.ContextNotActiveException: WELD-001303 No active contexts for scope type javax.faces.view.ViewScoped

JSF 2.2 requires additional changes for CDI support, an EE 7 server should be used.
