Parameterübergabe einer Seite zu einer anderen Seite in JSF-2.0?

Ich möchte ein parameter übergeben werden, von einer Seite zur anderen.

Jeder Seite wird eine ViewScoped JSF Backing Bean.

Obwohl, ich versuche es mal mit <f:param> bekomme ich die folgende Fehlermeldung:
wenn ich auf <h:commandLink> wird navigieren Sie zu einer anderen Seite.

FEHLER :

] Root cause of ServletException.
com.sun.faces.mgbean.ManagedBeanCreationException: Unable to create managed bean ReservationActionBean.  The following problems were found:
     - The scope of the object referenced by expression #{param.resvDataModel}, request, is shorter than the referring managed beans (ReservationActionBean) scope of view
