    public boolean isSelectedFileUpload(){

推荐答案

您可以定义 p：remoteCommand 只是更新对话框，并在 onShow 属性中调用该命令：

You can define p:remoteCommand which just update dialog, and call that command in onShow attribute:

<p:remoteCommand name="updateDialog" update="saveDialogPanel"/>

<p:dialog widgetVar="pictureSaveDialog" id="pictureDialog" closable="false" onShow="updateDialog()">

如果您的 saveDialogPanel 在某些命名容器中可以添加适当的前缀以匹配组件的ID。

If your saveDialogPanel is in some naming container be shore to add appropriate prefix to match id of component.
