```
public class RequestStateManager
extends Object
```
This helper class is used a central location for per-request state that is needed by Mojarra. This class leverages FacesContext.getAttributes() which as added in 2.0 instead of the request scope to prevent the unecessary triggering of ServletRequestAttributeListeners.
