我有这个命令按钮
<p:commandButton onclick="confirmation1.show()"
id="delFriend" title="Delete #{userFriend.profileFullname}" icon="ui-icon ui-icon-trash" >
</p:commandButton>
这是确认对话框
<p:confirmDialog id="confirmDialog" message="Are you sure you want to delete this friend ?"
header="Deleting friend" severity="alert" widgetVar="confirmation1">
<p:commandButton id="confirm" value="Yes Sure" oncomplete="confirmation1.hide()"
action="#{messagesManagedBean.deleteFriend}">
<f:param value="#{profileId}" name="profileId" />
</p:commandButton>
<p:commandButton id="decline" value="Not Yet" onclick="confirmation1.hide()" type="button" />
</p:confirmDialog>
两者都在 ui：repeat 中，当我单击确认对话框中的"是的确定"按钮时，它会获取 ui：repeat 列表中存在的最后一个元素的 profileId。
我尝试了 f：param 方法，然后尝试在 bean 中获取请求参数，但徒劳无功。 它做同样的事情。
需要帮助。谢谢

在BalusC的回复之后。但它不起作用，使用 update="：interestExpressionsForm：confirmDialog"确认"对话框将打开，然后立即关闭。
将<p:confirmDialog>放在<ui:repeat>之外。您只需要一个，而不是多个。只需根据按下的按钮相应地更新对话框的内容。
