Package org.apache.wicket.validation
Interface INullAcceptingValidator<T>
- Type Parameters:
T
- type of validatable
- All Superinterfaces:

Marker interface for validators that will accept a
null
value. Without implementing
this interface Wicket will never pass null
values to
IValidator.validate(IValidatable)
.
Keep in mind that the FormComponent
must have set the required property to
false
, otherwise Wicket will not permit the validator to process the
null
value.
