I'm already doing like you, but I'd like to try the solution #1 explained by
Thomas Broyer, so the code is from that test. The class already extends
DialogBox and I get the error reported, the extends is missing because I
done something wrong with cut&paste.
I need @Inject because that class is the Display injected in a Presenter.
I want to try that solution because I prefer to extends DialogBox.
