getValidatorId
public String getValidatorId(FaceletContext ctx)
Retrieve the id of the validator that is to be created and added to the parent
EditableValueHolder. All subclasses should override this method because it is important for Facelets to have a unique way of identifying the validators that are added to thisEditableValueHolderand allows exclusions to work properly. An exclusion is a validator declaration that has the attribute "disabled" which resolves to false, instructing Facelets not to register a default validator with the same id.

getValidatorConfig
public ValidatorConfig getValidatorConfig()
Return the
TagConfigsubclass used to configure this handler instance.
