Fiz um exemplo com um sistema diferente que estava com o curso.
A primeira vez , após logar ele faz o logout tranquilo.
/**
* Efetua logout na aplicação
*/
public String logout() {
face.getExternalContext().getSessionMap().remove("usuarioLogadoSistema");
logger.info("Usuário fez logout.");
return "index?faces-redirect=true";
}Se vou em outra página, ele retorna exceção.
No caso: /endereco/pais/pais.xhtml
