JSF 2.0 Accessing Application Scope bean from another Bean

Question

I am using jsf 2.0 and I have two bean Navigation (Application Scope ) and Module (Request Scope). I want to use methods of Navigation bean in Module Bean. I am doing in thi

Answer 1

The both beans needs to be a fullworthy @ManagedBean. The acceptor should have a public setter method for the injected bean. The injected bean is only available in @PostConstruct and beyond (i.e. in all normal event methods, but thus not in the constructor of the acceptor).

So, this ought to work:

@ManagedBean
@ApplicationScoped
public class Navigation {
    // ...
}

---

@ManagedBean
@RequestScoped
public class Module {

    @ManagedProperty(value="#{navigation}")
    private Navigation navigation;

    @PostConstruct
    public void init() {
        navigation.doSomething();
    }

    public void setNavigation(Navigation navigation) {
        this.navigation = navigation;
    }

}
