在 Java 中创建多个 PrimeFaces 对话框

Question

我想向用户显示多条警告消息。用户必须确认他已阅读。

我尝试了 PrimeFaces DialogFramework

PrimeFaces.current().dialog().showMessageDynamic(new FacesMessage(FacesMessage.SEVERITY_INFO, "Message-1", "message-1"), false);
PrimeFaces.current().dialog().showMessageDynamic(new FacesMessage(FacesMessage.SEVERITY_INFO, "Message-2", "message-2"), false);

但是第二次调用会覆盖对话框中的内容，用户只会看到第二条消息。

我试过JQueryUI，可以正确显示多个对话框，但很难将 PrimeFaces 样式添加到对话框中。

function showDialog(id, title, content) {
  var dialog = document.createElement("div");
  dialog.id = id;
  dialog.title = title;
  dialog.innerHTML = content;
  document.body.appendChild(dialog);
  $("#" + id).dialog({
    modal: true,
    buttons: {
      Ok: function() {
        $(this).dialog( "close" );
      }
    }
  });
}

$(function() {
  showDialog("dialog-1", "Message-1", "message-1");
  showDialog("dialog-2", "Message-2", "message-2");
});

有没有一种方法可以使用 PrimeFaces DialogFramework 来显示多个对话框，或者有一种简单的方法可以将 PF 样式添加到 JQuery-Dialog 中？

            PrimeFaces.current().ajax().update("my-form");
        }
    }
}

单击按钮时，bean 将创建三个对话框。我添加了一个确定按钮以获得用户的确认。如果单击创建的对话框将从文档中删除。
