我有一个带有primefaces 3.5的JSF 2.2.0-m12应用程序。由于我将应用程序从JBoss 7.1.1移植到Tomcat 7.0.39，因此在重新加载页面后第一次更改输入字段（inputtext，slider，button，...）工作正常，但第二次更改不起作用。我搜索了第一个和第二个请求之间的差异：
第一次请求：
contentForm contentForm contentForm:inputZinsatz 2.0 contentForm:j_idt157:anla... 277 contentForm:j_idt157:maxA... 25 contentForm:j_idt157:slid... 277 contentForm:j_idt72:saveA... 10000 contentForm:j_idt72:saveA... 20000 contentForm:selectSparArt false javax.faces.ViewState -1622287370124327744:4775655032591022279 javax.faces.behavior.even... slideEnd javax.faces.partial.ajax true javax.faces.partial.event slideEnd javax.faces.partial.execu... contentForm:j_idt157:sliderAnlageDauer javax.faces.partial.rende... contentForm javax.faces.source contentForm:j_idt157:sliderAnlageDauer
第二次请求：
contentForm contentForm contentForm:inputZinsatz 2.0 contentForm:j_idt157:anla... 460 contentForm:j_idt157:maxA... 25 contentForm:j_idt157:slid... 460 contentForm:j_idt72:saveA... 10000 contentForm:j_idt72:saveA... 20000 contentForm:selectSparArt false javax.faces.behavior.even... slideEnd javax.faces.partial.ajax true javax.faces.partial.event slideEnd javax.faces.partial.execu... contentForm:j_idt157:sliderAnlageDauer javax.faces.partial.rende... contentForm javax.faces.source contentForm:j_idt157:sliderAnlageDauer
现在我不确定，如果缺少的ViewState导致错误的行为。
在我的页面中有三个不包含表格。对于每个表单，都是一个隐藏的viewstate标记，在outcoming html中呈现（浓缩）：

我尝试用这里描述的JS解决问题没有成功： h:commandButton/h:commandLink does not work on first click, works only on second click
以及web.xml中的以下配置：
<context-param>
<param-name>com.sun.faces.autoCompleteOffOnViewState</param-name>
<param-value>false</param-value>
</context-param>
<context-param>
<param-name>com.sun.faces.enableViewStateIdRendering</param-name>
<param-value>false</param-value>
</context-param>
被修改 这是xhtml页面：

如何将ViewStatus传递给服务器？丢失的ViewState可能是导致错误行为的原因吗？
感谢您的帮助。如果您需要更多信息，请询问！
答案 0 :(得分：2)
与BalusC和Jens一样，问题是Primefaces和JSF的版本：
PF 3.5不适用于JSF 2.2。你应该使用PF 4.0。请使用常规JSF组件进行测试，以排除PF 3.5的原因，或降级为JSF 2.1。
降级到JSF 2.1之后就可以了。
