问题描述
我是JSF的新手，我正在构建一个使用facelets创建的应用程序。
这是我的模板
master.xhtml
I am new to JSF and I am building a application created with facelets.
Here is my template

我认为由于这个原因，它没有提交按钮的动作
And I think due to this it is not submitting action of my button
< h：commandButton id =btnMasterSearchtype =submitvalue =SearchstyleClass =submitButtonaction = ＃{masterSearch.findPerson}> 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
<h:commandButton id="btnMasterSearch" type="submit" value="Search" styleClass="submitButton" action="#{masterSearch.findPerson}"> present in MasterSearch.xhtml.I found on SO that people had that problem but I am unable to find and understand a good solution.
please help thanks
推荐答案
这是Mojarra的一个已知错误。据报道 2215 和 2277 并自Mojarra 2.1.8起修复。所以如果你升级到至少2.1.8，那么这个问题应该会消失。
This is a known bug in Mojarra. It has been reported as issues 2215 and 2277 and has been fixed since Mojarra 2.1.8. So if you upgrade to at least 2.1.8, then this problem should disappear.
这个问题的原因可以解释如下：Mojarra试图推迟会话创造尽可能多。该会话应仅在真正需要时创建。其中，当需要写入< h：form> 的JSF视图状态时，通常在渲染结束时发生< /小时：形式> 。但是，在 2KB的书面HTML之后，关闭< / h：form> 的相对较大的页面出现，那么创建会话。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。
The cause of this problem can be explained as follows: Mojarra is trying to postpone the session creation as much as possible. The session should only be created at the moment when it is really needed. Among others, when the JSF view state of the <h:form> needs to be written, which normally happens during rendering of the closing </h:form>. However, on relatively large pages wherein the closing </h:form> appears after 2KB of written HTML, then it's too late to create the session. To create a session the server namely needs to set a cookie. However, to set a cookie, the response should not have been committed (the cookie namely needs to go in the response header). A server is by default configured to flush the response on every 2KB of written HTML.
如上所述，自Mojarra 2.1.8以来，此问题已得到修复。您可以下载最新版本此处。
As said, this issue is been fixed since Mojarra 2.1.8. You can download the latest version here.
