This advanced component is a custom <f:validator>
tag that registers a validator by validator
id on a UIComponent
object.
This tag is analogous to a Faces Converter
and is useful in the IDE solely to register a custom external
class that implements javax.faces.validator.Validator
and has been registered under a validatorId
in a faces-config.xml
file.
Use this tag only for a custom validator. If you want to use one of the standard validators, open the component's Properties window and set the validator property.
