Spring 消息不起作用。素面

我使用下一页。managedBean的方法可以工作，但不能显示消息：

我认为问题出在panel或panelGrid中。但另一方面，这种方法是从这个角度出发的。有人能帮我解决这个问题吗？我找到了原因。它是-ajax=“false”。我将其删除，并显示消息

查找差异。。。

 public void addProject(){
    FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_INFO, "You voting is saved", "Thank you for you chose");

    RequestContext.getCurrentInstance().showMessageInDialog(message);
 }
