- the TagConfig
subclass for this kind
of attached object.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 this EditableValueHolder
and
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.
public ValidatorConfig getValidatorConfig()
Return the TagConfig
subclass used to configure this handler instance.
