问题是，当我在对话框中单击值为“添加”的按钮时，没有调用 bean 中的函数“添加”（我注意到它system.out），我不明白为什么。那是对话框的一些限制，必须用onComplete标签或其他东西关闭吗？或者可能是因为我不能在对话框上使用按钮操作？希望可以有人帮帮我。谢谢你。我有我的 xhtml 页面：

<p:commandButton id="Bottone" value="Add" update="display" actionListener="#{addConfirmedPackageBean.Add()}" process=":form:display,:form:packages,@this"/>

您只需要处理对话数据。

解决方案：将 RequestScoped 更改为 ViewScoped（评论）
