GWT Activity and Editor Framework

Question

I´ve been working on some small projects using GWT MVP framework + GWT Editors framework. I have Views interfaces with fields declared like:

 @Path("field")
 IsEditor<ValueBoxEditor<Long>> getField();

Views implementations look like this:

@UiField
   IsEditor<ValueBoxEditor<Long>> field;
public IsEditor<ValueBoxEditor<Long>> getField(){
   return field;
}

In my Activitys I have referances to correspond Views and when I have to do(in Activity) something like this:

view.getField.setEnable(true);

I have to do cast to

((ValueBoxBase<Long>)view.getField()).setEnable(true);

After that I can't test this unit, because in my test I define behaviour of View to return Mock (IsEditor<ValueBoxEditor<Long>>) on view.getFiled() as result I get:

java.lang.ClassCastException: com.google.gwt.editor.client.IsEditor$
$EnhancerByMockitoWithCGLIB$$e8c00c36 cannot be cast to
com.google.gwt.user.client.ui.ValueBoxBase

What is best practiece to call Views components methods from Activity without doing casting?

Answer 1

Cast to HasEnabled instead of ValueBoxBase.

Answer 2

You need to use the ValueBoxEditor adapter method "of":

@UiField ValueBoxBase<Long> field;

public ValueBoxEditor<Long> getField(){
   return ValueBoxEditor.of(field);
}
