NullPointerException on clearSkinCaches
---------------------------------------
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, JSK 1.6.0u29
Reporter: Fab Mars
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

Well, clearSkinCackes uses only FacesContext.
static void clearSkinCaches(FacesContext context) {
context.getAttributes().remove(BASE_SKIN_KEY);
context.getAttributes().remove(SKIN_KEY);
}
If you check on the debugger, FC is indeed null then. That's unexpected and I'm
not sure this is normal.
