JSF Primeffaces在SelectOnemenu上重置输入值

Question

手动选择selectOneMenu id="格式"；

selectOneMenu id＝"；格式"；工作良好。但是在选择selectOneMenu id＝"1"的下拉值时；格式"；输入的字段输入值为空。

页面

Employee name[Mark]         Employee Type       [New]       
Format [Select some drop down value]
.

电流输出

Employee name[Entered Value Disappeared/null]           Employee Type       [Selected value disappeared/null]       
Format [Selected some drop down value]

预期输出

Employee name[Mark]         Employee Type       [New]       
Format [Selected Value]
.

我已尝试添加

<p:ajax event="valueChange" immediate="true" process="@form" />
The rendering fails if I add it for the selectOneMenu

我有下面的代码

main.xhtml

<h:form id="newFormBank" enctype="multipart/form-data">   
<h:panelGroup id="id">
<p:growl id="growl" sticky="true" showDetail="true" />
<p:wizard id="newBankWizard" showNavBar="true" widgetVar="bankWiz" flowListener="#{javaMB.wizardFlow}">

<p:tab id="pro" title="Banks">
<ui:include src="/jsf/xyz.xhtml" />                      
<ui:include src="/jsf/employeeloan.xhtml" />                

</p:tab>
</p:wizard> 
</h:panelGroup>
</h:form>

您的p:ajax语句是错误的，它可能读起来像：

<p:ajax event="valueChange" update="@form" />
