嵌套视图的演示者未初始化且无法处理其视图的事件

Question

I am facing an issue, when I do inject a nested view into my base view's constructor using @inject. I am not able to handle the nested view's events in it own presenter. Because of which I need to handle them in the Base View's presenter. I have 2 view and their respective presenter's : AppBaseView - AppBasePresenter; LoginView - LoginPresenter. I @inject LoginView into the AppBaseView. Now that I have to handle the Login Button event, I am not able to do so in the LoginPresenter, but need to handle it in the AppBasePresenter. No idea why does that happen. Am I missing anything? Any light on this issue would be higly appreciated.

Thanks.

If you are trying to inject the same view into multiple classes, remember that you have to mark it as @Singleton , or otherwise ensure that both classes receive the same instance. By default Guice and Gin create a brand new instance every time you inject a class. It's hard to tell from your description, but you might be adding an event listener to an instance that the presenter owns and then displaying a different instance in your application.
