I've encontered the same problem and it took me a while to figure it out why.
So maybe it's a good idea to make it automatic on the framework, On all TextField<E> constructors without the type parameter we should call setType() like this: setType((Class<?>) ((ParameterizedType) getClass().getGenericSuperclass()).getActualTypeArguments()[0]); Too complicated??
