没有发送ViewState

tomcat

我有一个带有primefaces 3.5的JSF 2.2.0-m12应用程序。因为我将应用程序从JBoss 7.1.1移植到Tomcat
7.0.39,所以在重新加载页面后对输入字段(输入文本,滑块,按钮等)的第一个更改可以正常工作,但是第二个更改则无济于事。我搜索了第一个请求和第二个请求之间的区别:

第一个要求:

  • JSF阶段:执行从1到6的阶段
  • 在Firebug中,“网络->所有-> POST zinsrechner.xhtml->发布”是一个视图状态:

    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

第二个要求:

  • JSF阶段:在阶段1之后执行6
  • 在Firebug的’网络- >所有- > POST zinsrechner.xhtml - >后’是 没有 的视图状态:

    contentForm contentForm
    contentForm:inputZinsatz 2.0
    contentForm:j_idt157:anla … 460
    contentForm:j_idt157:maxA … 25
    contentForm:j_idt157:滑动… 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,是否缺少ViewState导致错误的行为。

在我的页面中,有三种不包含表格的形式。对于每种形式,都会在即将出现的html(压缩)中呈现一个隐藏的viewstate标签:

<!DOCTYPE html>

我尝试无法解决此处所述的JS问题:h:commandButton/h:commandLink在第一次单击时不起作用,仅在第二次单击时有效

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>

如何将ViewStatus传递给服务器?缺少ViewState可能是错误行为的原因吗?

谢谢你的帮助。如果您需要更多信息,请询问!

就像BalusC和Jens所说的那样,问题是Primefaces和JSF的版本:

PF 3.5不是为JSF 2.2设计的。您应该为此使用PF 4.0。请使用常规JSF组件进行测试以排除PF 3.5的原因,或降级到JSF 2.1。

降级到JSF 2.1后,它可以工作。
