Hey Chris,
Take a look here for one of the ways of doing this:
http://code.google.com/p/handlebars/
The view composition would be done in bindView() method in the
Presenter (it's in the interface, none of the default presenters
implement it in the package).. it usually looks like:
@Override
public void bindView() {
getView().setOneOfMyChildViews(getChildPresenters().get(MyChildPresenter.name).makeView().createAndBind());
}
Haven't seen gwt-platform before. Looks interesting...
