zf2会话验证失败

我正在使用zf2、rbcomments、条令、zfcuser和samuser实体。。。我有一个问题，在启动之前，我的应用程序抛出"会话验证失败"错误。除了身份验证（由zfcuser完成，而不是手动完成）之外，我在任何地方都不使用会话。这是调用堆栈：

更多可能有帮助的信息（唯一尚未添加的侦听器）：

public function onBootstrap(MvcEvent $mvcEvent)
{
    $zfcServiceEvents = $mvcEvent->getApplication()->getServiceManager()->get('zfcuser_user_service')->getEventManager();
    $zfcServiceEvents->attach('register', function($e) use($mvcEvent) {
        $app = $mvcEvent->getApplication();
        $sm = $app->getServiceManager();
        $user = $e->getParam('user');
        $entityManager = $sm->get('Doctrine'ORM'EntityManager');
        $roleRepo = $entityManager->getRepository('SamUser'Entity'Role');
        $defaultRole = $roleRepo->findOneBy(array('id'=>2));
        $user->addRole($defaultRole);
    });
}

我尝试了一些事情（比如在供应商中打印会话，似乎没有什么问题）。。。有什么想法吗？

附言：我怀疑这与布局有关，我试图通过使用if(!$this->zfcUserIdentity()){ 来查看用户是否具有身份
