ValidatorELTag. The remainder of the functionality, namely,
the binding facility and the implementation of the createValidator() method, is now an implementation detail.@Deprecated public class ValidatorTag extends TagSupport
ValidatorTag is a base class for all Jakarta Server Pages custom actions that create and register a
Validator instance on the EditableValueHolder associated with our most immediate surrounding
instance of a tag whose implementation class is a subclass of UIComponentTag. To avoid creating duplicate
instances when a page is redisplayed, creation and registration of a Validator occurs only
if the corresponding UIComponent was created (by the owning UIComponentTag) during the execution of
the current page.
This class may be used directly to implement a generic validator registration tag (based on the validator-id
specified by the id attribute), or as a base class for tag instances that support specific
Validator subclasses. This id attribute must refer to one of the well known validator-ids, or a
custom validator-id as defined in a faces-config.xml file.
Subclasses of this class must implement the createValidator() method, which creates and returns a
Validator instance. Any configuration properties that specify the limits to be enforced by this
Validator must have been set by the createValidator() method. Generally, this occurs by copying
corresponding attribute values on the tag instance.
This tag creates no output to the page currently being created. It is used solely for the side effect of
Validator creation.
