Hi,
I have a form with two required fields for example: "age" and "dateOfBirth",
all of them are required, but if they are in special group, then only one of
them is required.
In my custom class CustomFieldBlocks.java which implements
PropertyOverrides, I should return field validator for the field.
The main question is: How to implement custom validator with only one
required field from set of fields.
For example :
private FieldValidator getValidator(Field field) {
FieldValidator contextValidator = context.getValidator(field);
PropertyModel propertyModel =
beanModel.getById(context.getPropertyId());
String propertyLabel = propertyModel.getPropertyName();
if (propertyModel != null &&
mandatoryCustomFields.contains(propertyLabel)) {
List<Field> fields = new ArrayList<Field>();
// here I want to get all required fields for pass
for (String fieldLabel : mandatoryCustomFields){
Field field = ?????
fields.add(field);
}
GroupValidator groupValidator = new GroupValidator(fields,
"groupValidator");
return new
CompositeFieldValidator(Arrays.asList(groupValidator, contextValidator));
} else {
FieldValidator required =
fieldValidatorSource.createValidator(field, "required", null);
return new CompositeFieldValidator(Arrays.asList(required,
contextValidator));
}
return contextValidator;
}
