You need to remove the @RequestScoped and other related annotations from the UIBaseBean (and make it abstract).

Once that is done, you also need to fix the @ManagedProperty on #{param} to be either defined by or to be obtained by ExternalContext#getRequestParameterMap() instead.

JSF would throw an exception on that during bean's construction.
