杜松子酒在Gwt项目中的奇怪行为

For some inexplicable reason for me ,Gin does not works as i intend. Let me explain with little code.

对于我来说有些莫名其妙的原因,杜松子酒并不像我想的那样有效。让我用小代码解释一下。

Let say i have a formA

假设我有一个formA

@Singleton
public class formA extends Composite

    private final MyGinjector ginjector;

    @Inject
    public formA(MyGinjector ginjector)
    {
      this.ginjector = ginjector;
      this.add(ginjector.getFormB());
      this.add(ginjector.getFormC());   
    }

here are and formB and formC (let assume formB and formC has similar code)

这里是和formB和formC(假设formB和formC有类似的代码)

@Singleton
public class formB extends Composite
{
@Inject
public formB(MyGinjector ginjector)
{
  this.ginjector = ginjector;
..............
}
}

And the problem i has been facing is in some moment when i inject formA (ginjector.getFormA() return an instance of formA but with missing childWidgets meaning with no reference to formB and formC

我遇到的问题是在我注入formA的某个时刻(ginjector.getFormA()返回一个formA的实例,但缺少childWidgets意味着没有引用formB和formC

What could be the problem? all forms are singleton ... probably i should not inject the ginjector like that?

可能是什么问题呢?所有的形式都是单身......可能我不应该像那样注射那些ginjector?

Thanks

I believe gin does not support injecting the injector: gin groups discussion.

我相信杜松子酒不支持注射注射器:杜松子酒小组讨论。

Is there any reason you try injecting injector instead od injecting dependencies directly?

您是否有任何理由尝试直接注射注射器而不是注射依赖性?

You should just inject dependencies directly:

你应该直接注入依赖项:

    @Inject
    public formA(FormB formB, FormC formC){
