Answer 1

You shouldn't manage a single bean by multiple different bean management frameworks like JSF, CDI and Spring. Choose the one or the other. When managing the bean by for example Spring's @Controller, all bean management related annotations of other frameworks like JSF's @ManagedBean and CDI's @Named are ignored.

I don't do Spring and I have no idea why you're using it instead of the standard Java EE 6 API, but the symptoms and documentation indicates that the scope of such a Spring bean indeed defaults to the application scope. You need to specify the bean scope by Spring @Scope annotation. You would also like to remove the JSF bean management annotations since they have no value anymore anyway and would only confuse the developer/maintainer.

@Controller
@Scope("request")
public class MyBean implements Serializable {
    // ...
}

Alternatively, you can also get rid of Spring @Controller annotation and stick to JSF @ManagedBean. You can use @ManagedProperty instead of @Autowired to inject another @ManagedBean instance or even a Spring managed bean (if you have Spring Faces EL resolver configured), or the Java EE standard @EJB to inject an @Stateless or @Stateful instance.

E.g.

@ManagedBean
@RequestScoped
public class MyBean implements Serializable {

    @EJB
    private SomeService service;

    // ...
}
