Any progress on this? I met the same issue today.

<f:metadata>

     <f:event listener="#{loginRequiredListener.loginRequired}" type="preRenderView"></f:event>

</f:metadata>

public void loginRequired() throws IOException{
        if(loggedInUserInstance.get() == null){
            HttpServletRequest request = (HttpServletRequest) facesContext.getExternalContext().getRequest();
            originalRequest = request.getRequestURI();
            log.info(originalRequest);
            facesContext.getApplication().getNavigationHandler().handleNavigation(facesContext, null, "login");
//            facesContext.getExternalContext().redirect("/login.jsf");
        }
    }

<navigation-rule>

        <navigation-case>

            <from-outcome>login</from-outcome>

            <to-view-id>/login.xhtml</to-view-id>

            <redirect></redirect>

        </navigation-case>
