Question

我目前正在开发一个我想要使用bootsfaces的项目。应用程序处于运行状态。我只是为了外表重建它。

之前，有一个richFaces navigationBar工作正常，我用bootstraps默认导航栏替换它。所以我调整了所有的导航链接和标签，但唯一不起作用的是Logout-Button。

navigation.xhtml：

SessionScoped LoginBeans方法：

public String logout() {
    HttpSession session = SessionUtils.getSession();
    session.invalidate();
    return "index";
}

进入页面时出错：The class 'de.carsharing.beans.LoginBean' does not have the property 'logout'.

如果我将其设为action="#{loginBean.logout()}"，则会加载页面，但点击按钮时不会调用该方法。

我已经阅读了ui:components内部commandButtons的一些问题，所以我试图手动包含它，但它没有帮助。将它放在一个看不见的h：form中也一样。

我不知道，可能是，b：commandButtons＆＃34; action＆＃34;属性不是作为MethodExpression计算，而是作为ValueExpression计算？

BootsFaces CommandButton不会在BackingBean中触发操作
