java - Vaadin ConfirmDialog 自定义

Question

我对对话框的问题是有时第三个按钮不显示。它在测试期间显示出来，但让代码在 git 中腐烂一天并重新测试它，它只显示两个按钮。

package com.xxx.bpspkpibpcheck.dialog;

import org.vaadin.dialogs.ConfirmDialog;

import com.xxx.bpspkpibpcheck.message.UIMessageByLocaleService;
import com.vaadin.ui.UI;

/**
 * Class representing the save as disabled dialog
 */
public class SaveAsDisabledDialog {
    //translation prefixes
    //private static final String DIALOG = "Dialog.";
    private static final String SAVEASDISABLEDDIALOG = "SaveAsDisabledDialog.";

    //translation postfixes
    //private static final String MESSAGE_DISACTIVATE = "message.disactivate";
    private static final String MESSAGE_CANCEL = "message.cancel";
    private static final String CAPTION_SAVEASDISABLED = "caption.saveasdisabled";
    protected static final String MESSAGE_YES = "message.yes";
    protected static final String MESSAGE_NO = "message.no";
    private static final String MESSAGE_SAVEASDISABLED = "message.saveasdisabled";

    protected static final String TOOLTIP_YES = "tooltip.yes";
    protected static final String TOOLTIP_NO = "tooltip.no";
    protected static final String TOOLTIP_CANCEL = "tooltip.cancel";

    //factories
    ConfirmDialog.Factory oldFactory;
    ConfirmDialog.Factory factory;

    /**
     * Construct a SaveAsDisabledDialog
     * @param messageByLocaleService
     */
    public SaveAsDisabledDialog(UIMessageByLocaleService messageByLocaleService) {
        oldFactory = ConfirmDialog.getFactory();
        factory = new ConfirmDialog.Factory() {

            @Override

                ConfirmDialog cd = oldFactory.create(messageByLocaleService.getMessage(SAVEASDISABLEDDIALOG + CAPTION_SAVEASDISABLED),
                        "message",
                          "xxx", //messageByLocaleService.getMessage(DIALOG + MESSAGE_CANCEL),

                cd.setMessage(messageByLocaleService.getMessage(SAVEASDISABLEDDIALOG + MESSAGE_SAVEASDISABLED));

                /*

                cd.getOkButton().setCaption(messageByLocaleService.getMessage(SAVEASDISABLEDDIALOG + MESSAGE_YES));
