Examples of org.apache.tapestry.services.FieldValidatorSource.createValidator()

org.apache.tapestry.services.FieldValidatorSource.createValidator()

Creates the validator. The error message associated with the field validator usually comes from the {@link ValidationMessagesSource} (using the validator's{@link Validator#getMessageKey() message key}). However, if the container component of the field defines a message key

id-validator (where id is the simple id of the field component, and validator is the validatorType), then that message is used instead. This allows you to override the message for a particular validation of a particular field.
@param field the field for which a validator is to be created
@param validatorType used to select the {@link Validator} that forms the core of the{@link FieldValidator}
@param constraintValue a value used to configure the validator, or null if the validator is not configurarable
@return the field validator for the field
