Hmm... And what about work done using IObjectClassAwareModel?
It seems to work for me, I never need to pass

I am getting a ClassCastException when using RangeValidator like this:
RequiredTextFieldInteger intField = new
RequiredTextFieldInteger(intField);
intField.add(new RangeValidator(0, 100));

RequiredTextFieldInteger intField = new
RequiredTextFieldInteger(intField);
