-------------------------
Resolution: Rejected
JSF impl issue.
> NPE on clearSkinCaches after HttpServletRequest wrapping
> --------------------------------------------------------
>
> Key: RF-11809
> URL: https://issues.jboss.org/browse/RF-11809
> Project: RichFaces
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Affects Versions: 4.1.0.CR2
> Environment: Win7 x86, Glassfish 3.1.2 promoted, JDK 1.6.0u29
> Reporter: Fab Mars
> Labels: glassfish_v3, jsf21, richfaces4, skin, waiting_on_user
>
> 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/before.
> 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
