JSF複雜的形式 - 綁定錯誤

Question

我有一些輸入一種形式，具有ViewScoped * ManagedBean *後面。在窗體的底部我有一個CommandButton來保存數據。有一個數據表的形式可以添加新的項目通過輸入數據到輸入並點擊另一個CommandButton。當用戶填充所有輸入並將任何項目添加到數據表時，他/她可以單擊保存按鈕。但是我在控制添加按鈕和更新數據模型方面遇到了一些問題。當我將按鈕的無形設置爲true時，輸入的值不會更新，並且當我將其設置爲false時，驗證錯誤將發生在窗體上的其餘輸入上！

如果它可以幫助

Answer 1

的h:commandButton提交整個窗體和所有的元素將被驗證。您可以使用ajax進行部分提交。請嘗試以下操作：

爲您的數據表提供一個id值。所以，你可以從你的commandButton引用它：

<h:panelGroup id="tableWrapper"> 
<h:datatable id="mytable" value="#{requestWaggon.waggonsDataModel}" ..> 
     ... 
</h:datatable> 
</h:panelGroup> 

然後把一個< f:ajax>您的commandButton內。 render和execute屬性必須包含您的數據表的標識;不需要immediate=true：

<h:commandButton value="#{lbls.add}" action="#{requestWaggon.addWaggon}"> 
    <f:ajax render="tableWrapper" execute="mytable"/> 
</h:commandButton>
