The rawInput variable is set in the FormComponent when the validation
starts. If validation succeeds, rawInput is set to an internal constant and
processing continues. If validation fails, the rawInput for each
FormComponent is still available and is rendered on the input page.
As far as adding an IntegerValidator to a TextField, it's pretty simple:
TextField age = new TextField("age");
age.add(IntegerValidator.range(0, 130));
add(age);
The last call adds the TextField to the Form object.
