HasValueIt is acceptable to fail assertions or throw (documented) unchecked exceptions in response to bad values.
Widgets must accept null as a valid value. By convention, setting a widget to
null clears value, calling getValue() on a cleared widget returns null. Widgets
that can not be cleared (e.g. CheckBox) must find another valid meaning
for null input.

HasValueValueChangeEvent when
fireEvents is true and the new value does not equal the existing value.
It is acceptable to fail assertions or throw (documented) unchecked exceptions in response to bad values.
