Hi! I'm having some trouble getting polymorphic classes to work with the Object Binding API. I copied the example from the readme exactly, but when I try to parse the json, I get Unable to instantiate Rectangle with parameters [] as an error. As far as I can tell, it expects the width and height fields to exist on the Shape class itself. Does anyone know why this might be?
