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,重新加载页面后输入字段(输入文本、滑块、按钮...)的第一次更改工作正常,但第二次更改没有任何作用。我搜索了第一个和第二个请求之间的差异:
第一个请求:
- JSF 阶段:执行阶段 1 到 6
- 在 Firebug 'network -> all -> POST zinsrechner.xhtml -> post' 中是一个视图状态:
内容形式 内容形式 contentForm:inputZinsatz 2.0 contentForm:j_idt157:anla... 277 contentForm:j_idt157:maxA... 25 内容形式:j_idt157:滑动... 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 真 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
第二个要求:
- JSF 阶段:在第 1 阶段之后执行第 6 阶段
- 在 Firebug 'network -> all -> POST zinsrechner.xhtml -> post' 中没有视图状态:
内容形式 内容形式 contentForm:inputZinsatz 2.0 contentForm:j_idt157:anla... 460 contentForm:j_idt157:maxA... 25 contentForm:j_idt157:slide... 460 contentForm:j_idt72:saveA... 10000 contentForm:j_idt72:saveA... 20000 contentForm:selectSparArt false javax.faces.behavior.even... slideEnd javax.faces.partial.ajax 真 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
现在我不确定是否缺少 ViewState 会导致不正确的行为。
在我的页面中有三个不包含的表格。对于每个表单,在输出的 html(压缩)中呈现一个隐藏的 viewstate 标记:

我尝试使用此处描述的 JS 解决问题,但未成功: h:commandButton/h:commandLink 在第一次单击时不起作用,仅在第二次单击时起作用
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>
编辑 这是xhtml页面:

我该怎么做才能将 ViewStatus 传递给服务器?丢失的 ViewState 可能是导致错误行为的原因吗?
谢谢你的帮助。如果您需要更多信息,请询问!
