通过ui:include从包含的页面触发bean方法

我想用JSF发送电子邮件。我成功地创建了一个发送电子邮件的页面，但是当我从主菜单动态调用这个页面时，它出现在页面的中心，但是一些框没有出现，最糟糕的是:Bean根本不工作。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bean的所有功能，或者如何从这个页面调用bean。注意:它的工作，只是停止当它在主页。

因为我也有问题直接调用我的Bean的方法sendMail2()，目前我调用属性的setter(因为它有效)，并在这个setter方法中调用sendMail2()。

页面:

        </h:form>

正如Luigi Mendoza所说，解决方案是使用模板，先使用ui:insert，然后使用ui:composition。以下是我的工作解决方案:
