In IE (but not Mozilla/Firefox) empty request parameters may be returned
to JSF as the string "null". JSF always "restores" some idea of the
last view, even if that idea is always going to be null because a redirect
has occurred. Put these two things together, and you end up with
a class cast exception when redirecting from this request-scoped
bean to a static page.
