grails - ifNotLoggedIn标签-Grails 2.4.4/Spring Security 2.0-RC4-无法在空对象上获取属性 'securityConfig'

Question

奇怪的问题在这里。我的模板gsp中有一个sec:ifNotLogged in标记，它失败并显示以下错误/堆栈跟踪。但是，如果删除标签以便可以登录，然后在登录后再添加回标签，则可以正常工作。我有一个扩展了Spring Security插件以添加REST身份验证提供程序的插件，但是相同的配置在Grails 2.3.8和Spring Security 2.0RC2上也可以使用。

用户错误。在标签正文中的模板中引用SpringSecurityUtils的旧软件包。
