ManagedBean accessing another ManagedBean

I'm probably really close to the solution but I'm new with JSF and I don't see my mistake. I have a first SessionScoped Managed Bean that represents Business information (address, website, ...)

@Named(value = "businessController")
@SessionScoped
public class BusinessController implements Serializable {
    private Business current;
    @EJB private BusinessFacade ejbFacade;
    ....

I have a second SessionScoped Managed Bean that represents the logged in user

@Named(value = "loginController")
@SessionScoped
public class LoginController implements Serializable {

    private Login current;
    @EJB
    private LoginFacade ejbFacade;
    @ManagedProperty(value="#{businessController}")
    private BusinessController businessController;

    public BusinessController getBusinessController() {
        return businessController;
    }

    public void setBusinessController(BusinessController businessController) {
        this.businessController = businessController;
    }

When a user logs in, I set the current attribute from the loginController Depending on this current user, I want to set the business attribute from the businessController :

businessController.setCurrent(current.getBusiness());

My problem is that the businessController attribute is null !

I use NetBeans 7.0.1 and GlassFish 3.1 In debug mode, I can see a viewId variable with the value 

>No current context (stack frame)<

Unfortunately it doesn't ring any bell to me.

Any help would be appreciated Thanks

You are mixing JSF managed beans with CDI managed beans.

Your BusinessController is annotated with the CDI annotaion @Named but gets injected with the @ManagedProperty annotation (from JSF). CDI managed beans need to be injected with @Inject. No getter or setter needed in this case. If you tend to use CDI, make sure that you import the correct @SessionScoped:

CDI: javax.enterprise.context.SessionScoped

JSF: javax.faces.bean.SessionScoped

Try the following (After making sure to have the correct scope class imported):

 @Inject private BusinessController businessController;
