Nie rozumiem takiej sytuacji (java + jsf):
public class X implements Serializable {...}
public class X1 extends X implements Serializable {...}
public class X2 extends X implements Serializable {...}
public class Run {
@Inject X y;
...
}
Oczywiście y może być (w innym miejscu kodu) X1 lub X2 w zależności od
pewnego wyboru.
W linii z @Inject mam uwagę kompilatora: "Unresolved ambiguous
dependency found as result of type safe resolution"
I program mi się nie uruchamia.
Z logu serwera jest:
Possible dependencies:
- Managed Bean [class newpackage.X1] with qualifiers [@Default @Named @Any],
- Managed Bean [class newpackage.X] with qualifiers [@Default @Named @Any],
- Managed Bean [class newpackage.X2] with qualifiers [@Default @Named @Any]
Dlaczego tak się dzieje?
