You can define p:remoteCommandwhich just update dialog, and call that command in onShowattribute:
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()">
If your saveDialogPanelis in some naming container be shore to add appropriate prefix to match id of component.
如果您saveDialogPanel在某个命名容器中，请添加适当的前缀以匹配组件的 id。

You better refresh the dialog content before its being open
您最好在打开之前刷新对话框内容
Your p:commandButton/p:ajax should have the following:
您的 p:commandButton/p:ajax 应具有以下内容：
update="pictureDialog" onsuccess="pictureSaveDialog.show()"
