Re: Spring ROO GWT with GIN injection on widgets created by ui:binder.

It feels like I'm working in circles, one module needs something from another module and that one needs stuff from another module etc etc etc

Here's my updated code using the container method:

RorPresenter.java

public class RorPresenter {

    private RorView view;

    public void setView(RorView view){

        this.view = view;

    }

    @Inject

    public RorPresenter(){

        bind();

    }

    public void doMyClickEvent(){

        Window.alert("FIT");

    }

    public void doYourClickEvent(){

        Window.alert("MEH");

    }

    public void bind(){}

}

RorView.java

public class RorView {

    interface Binder extends UiBinder<Widget, RorView> {}

    private static Binder BINDER = GWT.create(Binder.class);

    private RorPresenter presenter;

    @Inject

    public RorView(RorPresenter presenter){

        this.presenter = presenter;

        presenter.setView(this);

        presenter.bind();

    }

    @UiHandler("myButton")

    void onMyButtonClick(ClickEvent event){

        presenter.doMyClickEvent();

    }

    @UiHandler("yourButton")

    void onYourButtonClick(ClickEvent event){

        presenter.doYourClickEvent();

    }

}

RorContainer.java

public class RorViewContainer extends Composite {

    interface Binder extends UiBinder<Widget, RorViewContainer> {}

    private static Binder BINDER = GWT.create(Binder.class);

    @UiField(provided=true)

    RorView view;

    @Inject

    @UiConstructor

    public RorViewContainer(RorView view){

        this.view = view;

        initWidget(BINDER.createAndBindUi(this));

    }

    @UiFactory RorViewContainer makeRorViewContainer(){

        return new RorViewContainer(this.view);

    }

}

And now I use <ig:RorViewContainer  /> in the applicationscaffold's xml configu.

It doesn't like the paramaters in the constructor and the @UiFactory doesn't fix it

[ERROR] <ig:RorViewContainer> missing required attribute(s): view Element <ig:RorViewContainer> (:156)

Jeff, can I mail you my maven project sample code, it'll be easier to show the problem if you have the whole context under eyes, been struggling to bind the view and the presenter for literally weeks now, just need one working example.

Thanks

J

Sorry, I had forgotten you're using Roo. I don't have much experience with Roo/gwt but here is one way to get it done. This might not be the optimal way though since I haven't played around with the Roo/gwt framework for more than about an hour as I'm not able to use it in my current projects. 

Is the presenter generated for you by Roo or is that your own implementation? If it is your own, you could remove the Display from the constructor and add a setter for it instead. 

Here is what your uiBinder class could look like.

The only catch here is everywhere you use this, you'll have to do a

public class RorViewContainer extends Composite {

.. uibinder boilerplate...

UiField(provided=true)

RorView view;

@Inject

public RorViewContainer(RorView view){

   this.view = view;

        initWidget(uiBinder.createAndBindUi(this));

}

private RorPresenter presenter;

@Inject

RorView(RorPresenter presenter){

  this.presenter = presenter;

  presenter.setView(this);

  presenter.bind();

}

@UiHandler("myButton")

public void myButtonClick(ClickEvent event){

    presenter.doMyClickEvent();

}

@UiHandler("yourButton")

public void yourButtonClick(ClickEvent event){

  presenter.doYourClickEvent();

}
