If a guest user requests a page which needs a login or a ssl protected page without ssl, seam tries to redirect to the login page or the same page using https protocol. To do this, Seam uses the external context redirect method. In the case of IceFaces ServletExternalContext the NullPointerException occurs, because in ServletExternalContext a redirector object is not initialized yet.
