Returns:ValidatorConfig

the TagConfig subclass used to configure this handler instance.

getValidatorIdback to summary
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.

Parameters
ctx:FaceletContext

the FaceletContext for this Facelet

Returns:String

the validator-id
