Deprecated
This has been partially replaced by ValidatorELTag. The remainder of the functionality, namely, the
binding facility and the implementation of the createValidator method, is now an implementation detail.
ValidatorTag is a base class for all JSP 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.
