Add items to List in Request Scoped Bean

Question

I have a backing bean as following:

@Named
@RequestScoped
public class ClientNewBackingBean {

    @Inject
    private ClientFacade facade;
    private Clien         


        

Answer 1

If you were using standard JSF bean management annotation @ManagedBean, you could have solved it by just placing the bean in the view scope by @ViewScoped.

@ManagedBean
@ViewScoped
public class ClientNewBackingBean implements Serializable {

    @EJB
    private ClientFacade facade;

    // ...

In CDI, the @ViewScoped however doesn't exist, the closest alternative is @ConversationScoped. You only have to start and stop it yourself.

@Named
@ConversationScoped
public class ClientNewBackingBean implements Serializable {

    @Inject
    private Conversation conversation;

    // ...

    @PostConstruct
    public void init() {
        conversation.begin();
    }

    public String submitAndNavigate() {
        // ...

        conversation.end();
        return "someOtherPage?faces-redirect=true";
    }

}

You can also use the CDI extension MyFaces CODI which will transparently bridge the JSF @ViewScoped annotation to work properly together with @Named:

@Named
@ViewScoped
public class ClientNewBackingBean implements Serializable {

    @Inject
    private ClientFacade facade;

    // ...

A CODI alternative is to use @ViewAccessScoped which lives as long as the subsequent requests reference the very same managed bean, irrespective of the physical view file used.

@Named
@ViewAccessScoped
public class ClientNewBackingBean implements Serializable {

    @Inject
    private ClientFacade facade;

    // ...
