确定按钮无法在vaadin中工作

Question

我有一个子窗口，其中包含一个文本字段和两个按钮确定和取消。当我点击确定按钮时，没有任何事情发生。我不明白我犯了什么错误。有人可以帮我弄这个吗。另外，我想知道如何将多个电子邮件地址放在一个由分号分隔的文本字段中。

这是我的代码

更新：大家好，我解决了这个问题。谢谢

OK按钮的代码

Button okButton = new Button("OK");
        okButton.addClickListener(new ClickListener()
        {
            private static final long serialVersionUID = 2387863967859745591L;
            @Override
            public void buttonClick(ClickEvent event)
            {
                if (confirmed())
                {
                    close();
                }
            }
        });
        buttonPanel.addComponents(cancelButton, okButton);
    }
