[weld-dev] Spec clarification needed

>>>Otherwise InjectionPoint#isDelegate() would always return false
No, Decorators are also beans and you can get its injection points with getInjectionPoints that one of them is @delegate therefore isDelegate returns true.

I think that "InjectionPoint injection" in the spec. has never written for that DependentScoped beans are injected into decorator delegates.

Thanks;

According to the java docs, I would also suppose your expression to be true. Otherwise InjectionPoint#isDelegate() would always return false, making this method dispensable. The interesting point imho is injecting the InjectionPoint in other cases than producer methods. I have not seen examples for this usage in the spec.
