LayoutComposite requires that its wrapped widget implement RequiresResize about gwtmockito HOT 2 CLOSED

Could you show how you're setting up your UiBinder? This seems to work for me:

interface MyUiBinder extends UiBinder<DataGrid, MyClass> {}
private final MyUiBinder uiBinder = GWT.create(MyUiBinder.class);
MyClass() {
  initWidget(uiBinder.createAndBindUi(this));
}

However, it only works if I declare the UiBinder to extend UiBinder<DataGrid, MyClass>, not UiBinder<Widget, MyClass>. This makes sense, since if you declare it to return a widget there's no way for GwtMockito to know you need to implement RequiresResize. Any chance this is the problem, or am I misunderstanding?

While debugging this I did find an unrelated bug that GwtMockito wasn't handling UiBinders that return a generic type properly - I fixed that in 8706592 in case you run into it.

You are absolutely right, that is the difference!

Though your bug fix seems like it could be related too, because my UI binder was defined like:

interface MyViewImplUiBinder extends UiBinder<Widget, MyViewImpl<T>> {}

from gwtmockito.
