我有两个页面page1.xhtml和page2.xhtml，其中包含简单的表单和h:commandLink。这些链接应调用bean void save1()中的方法void save2()和SendPaper。
第一个工作正常。它运行该方法并执行重定向到第2页。然而，第二个方法根本不会调用该方法。没有错误消息，没有服务器输出，没有。
我正在粘贴整个xhtml代码，因为我不知道这两个页面之间的区别是什么，为什么第一个有效，而第二个无效。
page1.xhtml：

更新：我认为它与复选框有关，即h:selectOneMenu。当我将其从page2.xhtml移至page1.xhtml时，page1.xhtml上的保存按钮停止工作。当我删除h:selectOneMenu时，按钮再次工作......
