> I have a homemade "pretty URL" mechanism I've been using on JSF1.2 and RF 3.3 in the past.
> It uses a phase listener that operates during RESTORE_VIEW.
> At the end of its parsing, it computes the "real" viewId to display and does:
>     PrettyUrlRequestWrapper wrapper = new PrettyUrlRequestWrapper(request);
>     wrapper.setViewId(computedViewId);
>     context.getExternalContext().setRequest(wrapper);
> When I don't use it and call directly .jsf pages, all works fine with RF 4.1.0CR2.
> When I use it, I get this error:
> GRAVE: null

> If you check on the debugger, FC is indeed null then. That's unexpected and I'm not sure this is normal.
