public abstract class ConverterELTag extends TagSupport
ConverterELTag is a base class for all Jakarta Server Pages custom
actions that create and register a
Converter instance on
ValueHolder associated with our most immediate
surrounding instance of a tag whose implementation class is a
UIComponentClassicTagBase. To avoid creating duplicate
instances when a page is redisplayed, creation and registration of a
Converter occurs only if the corresponding
UIComponent was created (by the owning
UIComponentTag) during the execution of the current page.
This class may be used as a base class for tag instances that
Subclasses of this class must implement the
createConverter() method, which creates and returns a
Converter instance. Any configuration properties that specify
behavior of this
Converter must have been set by the
createConverter() 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

public int doStartTag() throws JspException
Create a new instance of the specified
class, and register it with the
UIComponent instance associated
with our most immediately surrounding
UIComponentClassicTagBase instance, if
UIComponent instance was created by this execution of the
containing Jakarta Server Pages page. If the localValue of the
UIComponent is a String, attempt to convert it.
