Question

我正在使用代号构建我的第一个应用但是我认为在使用eclipse和新的GUI Builder时构建过程中存在一个错误。我是eclipse的霓虹灯，本周刚刚安装了cn1插件。

1）导致actionListeners无法工作的主要原因是EventCallbackClass中缺少一行

public void actionPerformed(com.codename1.ui.events.ActionEvent ev) {
            com.codename1.ui.Component sourceComponent = ev.getComponent();
            if(sourceComponent.getParent().getLeadParent() != null) {
                sourceComponent = sourceComponent.getParent().getLeadParent();
            }

            if(sourceComponent == gui_createAccount) {
             --------------missing------------------
            }
}

应该在那里调用 oncreateAccountActionEvent -method，但它不在生成的代码中。

它可能是因为我在构建期间遇到错误

2）点击＆＃34;动作事件＆＃34;时出现此错误在＆＃34;属性表＆＃34; - ＆GT; ＆＃34;活动＆＃34;图。

然而，控制台窗口对我来说很好看

感谢您的任何建议，也许我必须重新开始...

修改 - 解决方法：

在构造函数中指定action事件侦听器方法，如下所示：

 gui_createAccount.addActionListener((ev) -> {
             oncreateAccountActionEvent(ev);
        });

这是一个已经在其他IDE中修复的错误，但似乎仍然会影响Eclipse。一旦负责的工程师能够集合，我们就会尝试发布Eclipse更新。

代理一个ActionListener构建过程无法正常工作
