Ajax JSF Primefaces输入值在SelectOnemenu时重置

手动选择selectOneMenu id=“format”的值时，输入的输入值将重置

selectOneMenu id=“format”的渲染效果良好。但选择selectOneMenu id=“format”的下拉值后，输入的字段输入值为空

页面

电流输出

Employee name[Entered Value Disappeared/null]           Employee Type       [Selected value disappeared/null]       

Format [Selected some drop down value]

预期产量

Employee name[Mark]         Employee Type       [New]       

Format [Selected Value]
.

我试图补充一点

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

如果我将其添加到selectOneMenu，渲染将失败

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>

getters setters

您的p:ajax语句是错误的，它可能应该是这样的：

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