而且我认为由于这个原因，它没有提交我按钮的操作
<h:commandButton id="btnMasterSearch" type="submit" value="Search"styleClass="submitButton" action="#{masterSearch.findPerson}">目前在MasterSearch.xhtml。我对SO发现，人们有这样的问题，但我无法找到和理解一个好的解决方案。
请帮助谢谢
问题答案：
这是Mojarra中的一个已知错误。据报道，它是问题2215和2277，自Mojarra
2.1.8起已修复。因此，如果至少升级到2.1.8，则此问题应消失。
造成此问题的原因可以解释如下：Mojarra试图尽可能推迟会话的创建。该会话只能在 真正
需要的时候创建。其中，当<h:form>需要编写JSF视图状态时，通常在呈现close的过程中发生</h:form>。但是，在相对较大的页面上，其中关闭</h:form>出现
在
2KB的书面HTML之后，因此创建会话为时已晚。要创建会话，服务器即需要设置一个cookie。但是，要设置cookie，不应提交响应（即cookie需要放入响应头中）。默认情况下，服务器配置为每2KB的已编写HTML刷新响应。
如前所述，此问题自Mojarra 2.1.8起已得到修复。您可以在此处下载最新版本。
