Jsf 为什么我在对话框中使用primefaces获取以前的数据？

我不知道为什么当我使用从datatable调用的dialog时会得到以前的数据，当我打开对话框并将必填字段保留为空并按edit时，当我关闭对话框并打开另一行时，我注意到旧数据出现在字段中

这是我的密码

使用编辑命令按钮上的

更新=“：dialogForm”

。因此，每当您打开

对话框

，以前的数据都会被刷新。

不要将

p:dialog

放在

h:form

内，而是将

h:form

放在

p:dialog

内。
然后，您可以更新

h:form

或

h:panelGroup

中的

p:dialog

如果要从Javascript执行此操作，请使用

p:dialog

的

widgetWar

对象上的

loadContents（）

函数

例如：

<h:form id="form1">
    <p:commandButton update=":form2" oncomplete="myDialogWidget.loadContents()"/>
</h:form>

<p:dialog widgetWar="myDialogWidget" appendToBody="true">
    <h:form id="form2">
        ....
    </h:form>
</p:dialog>

....

它不起作用，我想当我点击edit with empty required data时，问题出在jsf验证中
