JSF Primefaces 輸入值在 SelectOnemenu 上重置

Question

輸入的輸入值在手動選擇 selectOneMenu id="format" 的值時重置

selectOneMenu id="format" 的渲染工作正常。 但是在選擇 selectOneMenu id="format" 的下拉值時，輸入的字段輸入值為空。

頁

Employee name[Mark]         Employee Type       [New]       

Format [Select some drop down value]
.

電流輸出

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

Format [Selected some drop down value]

預期產出

Employee name[Mark]         Employee Type       [New]       

Format [Selected Value]
.

我試圖添加

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

我有下面的代碼

主文件

    <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>

javaMB getters setters 實體 getters setters

Answer 1

你的 p:ajax 語句是錯誤的，它應該是這樣的：

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