代号一 ActionListener 构建过程不起作用

Question

我正在使用 codename one 构建我的第一个应用程序。
但是我认为在使用 eclipse 和新的 GUI Builder 时构建过程中存在错误。 我在 eclipse neon 上，本周刚安装了 cn1 插件。

1) 导致actionListeners不工作的主要原因是EventCallbackClass里面少了一行

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------------------
            }
}

应该在其中调用 oncreateAccountActionEvent 方法，但它不在生成的代码中。

这可能是因为我在构建过程中遇到错误

2) 在“属性表”->“事件”视图中单击“操作事件”时出现此错误。

'Building workspace' has encountered a problem. Errors occured during the build.

控制台窗口对我来说看起来不错

感谢您的建议，也许我必须重新开始......

编辑 - 解决方法：

在构造函数中指定动作事件监听方法，如下所示：

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

这是一个已在其他 IDE 中修复的错误，但似乎仍会影响 Eclipse。我们将尝试在负责的工程师召集后尽快发布 Eclipse 更新。
