[weld-dev] How to make method injection when bean subclass is required in Weld?

[Alex Sviridov]

Hi all,

I am really sorry for writing to this mailing list, but I checked all user forums and chats and saw that they are very old.

I would be very thankful if someone gives suggestion for solving the following problem. 
I have a child and parent class. Child has SimpleFoo, Parent needs Advaced foo. So,

@Dependent
public class SimpleFoo {
}

@Dependent
public class AdvancedFoo extends SimpleFoo {
}

@Dependent
public class Child {

    private SimpleFoo foo;

    @Inject
    protected void setFoo(SimpleFoo foo) {
        this.foo = foo;
    }
}

@Dependent
public class Parent extends Child {

    @Inject
    @Override
    protected void setFoo(SimpleFoo foo) { //How to inject here AdvancedFoo?
        super.setFoo(foo);
    }
}

How to inject in Parent AdvancedFoo? I know that I can do it via constructor injection 
but I need method injection. How to do it? Can it be done without using names (like MyBean1)
but only using classes (AdvancedFoo)?

Best regards, Alex
