而且我认为由于这个原因，我的按钮没有提交动作
出现在MasterSearch.xhtml 。我在SO上发现人们有这个问题但我无法找到并理解一个好的解决方案。
请帮助谢谢
这是Mojarra的一个已知错误。 据报道，问题是2215和2277 ，自Mojarra 2.1.8以来已经修复。 因此，如果您升级到至少2.1.8，那么此问题应该消失。
这个问题的原因可以解释如下：Mojarra试图尽可能地推迟会话创建。 该会话应仅在真正需要时创建。 其中，当需要写入 。 但是，在2KB的书面HTML 之后出现结束相对较大的页面上，创建会话为时已晚。 要创建会话，服务器即需要设置cookie。 但是，要设置cookie，不应该提交响应（cookie需要进入响应头）。 默认情况下，服务器配置为刷新每2KB书面HTML的响应。
如上所述，自Mojarra 2.1.8以来，这个问题已得到解决。 您可以在此处下载最新版本。
