How to create a MVP architecture with Vaadin + Spring?

Question

I'd like to create the following simple MVP architecture:

• View classes that are simly the vaadin layout, components, styles. nonfunctional. The views should be tied to the current ViewScope/SessionScope, therefore I use @UIScope of https://github.com/peholmst/vaadin4spring

• Presenters should have the view injected, register listeners on the view components, handle user input and delegate to the model services

Problem: when I inject the view into the presenter, the view is recreated, thus presenter and view are not in the same scope. So the binding will not work. What can I change to achieve the design described above?

@VaadinComponent
@UIScope
public class LoginView {
    //form fields, buttons
}

@Controller
public class LoginPresenter implements ClickListener {
    @Autowired
    private LoginView view;

    @PostConstruct
    public void bind() {
        view.getLoginButton().addClickListener(this);
    }   

    @Override
    public void buttonClick(ClickEvent event) {
        //validate input and login
    }   
}

Answer 1

Maybe something like

public class LoginView {

    @Autowired
    public void initPresenter(LoginPresenter loginPresenter) {
        loginPresenter.setLoginView(this);
        loginPresenter.bind();
    }
}

@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
public class LoginPresenter {

    private LoginView loginView;

    public void bind() {
        // ...
    }

    public LoginView getLoginView() {
        return loginView;
    }

    public void setLoginView(LoginView loginView) {
        this.loginView = loginView;
    }

}

Edit

You can decouple adding a configuration interface but adds some complexity, for example

    public interface View {

    }

    public interface Presenter {

        void setView(View view);
        void bind();
    }

    public interface ViewManager {

        void configure(View view);
    }

    public class ViewSupport implements View {

        @Autowired
        private ViewManager viewManager;

        @PostConstruct
        public void init() {
            viewManager.configure(this);
        }
    }



 /**
  * ViewManager that configure Presenters following 
  * the naming convention XXView->XXPresenter
  */  
 public class DefaultViewManager implements ViewManager {


    @Autowired
    private ApplicationContext applicationContext;

    @Override
    public void configure(View view) {
        Presenter p = (Presenter) applicationContext.getBean(getPresenterName(view.getClass()));
        p.setView(view);
        p.bind();

    }

    protected String getPresenterName(Class<?> clazz) {
        return StringUtils.uncapitalize(clazz.getSimpleName()).replace("View", "Presenter");
    }

}
