Question

我正在开发一些自定义屏幕和自定义操作，并希望在它们之间创建关联，就像添加“创建程序组”屏幕建议添加“创建程序组”操作一样。

所以我有一个屏幕，并希望将一个动作与它联系起来。该操作应放在“安装”屏幕上。在屏幕bean信息类中，我将以下行添加到构造函数中：

setAssociatedAction(MyAction.class.getName(), InstallationScreen.class.getName());

这似乎没有做任何事情。我重新编译，并重新添加屏幕到安装程序，但它不会提示我添加操作。我尝试将相同的设置添加到操作的构造函数中，认为可能两者都需要创建彼此的关联才能工作：

setAssociatedScreen(MyScreen.class.getName());
setInstallerTargetScreen(InstallationScreen.class.getName());

它也没有帮助。我甚至尝试通过创建动作来反过来查看是否请求创建屏幕，但是没有运气。幸运的是，设置安装程序目标屏幕按预期工作。

我也尝试了以下内容：

类名的简单和规范名称。
bean信息类，只是加入。

如果我做错了什么，我不确定我做错了什么。该文档不会包含任何其他依赖项：

希望这不是一个错误。

提前致谢！

修改

我即将解决此问题，但仅作为install4j的扩展。在BeanInfo中指定Bean类时，我使用了错误的类。

我有：

public MyActionBeanInfo() {
      super("Title", "Description", "Category", false, true, null, MyActionBeanInfo.class);
}

而不是：

public MyActionBeanInfo() {
      super("Title", "Description", "Category", false, true, null, MyAction.class);
}

作为一个小的增强，如果它不是一个有效的Bean类，是否可以从超级构造函数中抛出异常（可能是IllegalArgumentException）？

BUT！

当我没有用作扩展时，我仍然收到了ClassNotFound和NullPointer异常。

这是堆栈跟踪：

Answer 1

这是install4j中的一个错误。如果在安装程序 - >自定义代码＆amp;上添加bean，则无法加载关联的屏幕和操作。资源标签。

这将在5.1.7中修复。

setAssociatedAction（）和setAssociatedScreen（）不起作用
