我想用JSF发送电子邮件。我创建了成功发送电子邮件的页面，但是当我从主菜单动态调用此页面时，它出现在我的页面中心，但是有些框没有出现，最糟糕的是：Bean根本不起作用。 所以我的问题是我应该如何正确地包含这个页面，以便仍然使用Beans的所有功能，或者如何从这个页面调用bean。 注意：它可以工作，只是在主页面内停止。
因为我也有问题直接调用我的Bean的方法sendMail2（），此刻我调用属性的setter（因为它工作）并且在这个setter方法中我调用sendMail2（）。

Luigi Mendoza表示解决方案是使用模板，ui:insert然后ui:composition。这是我的工作解决方案：
