    public boolean isSelectedFileUpload(){

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

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

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

如果您saveDialogPanel在某个命名容器中,则添加适当的前缀以匹配组件的id.
