public class SetPropertyActionListenerTag
extends jakarta.servlet.jsp.tagext.TagSupport

Tag implementation that creates a special ActionListener instance and registers it on the ActionSource associated with our most immediate surrounding instance of a tag whose implementation class is a subclass of UIComponentClassicTagBase. This tag creates no output to the page currently being created.

The ActionListener instance created and installed by this tag has the following behavior and contract.

• Only create and register the ActionListener instance the first time the component for this tag is created
• The "target" and "value" tag attributes are ValueExpression instances and are stored unevaluated as instance variables of the listener.
• When the listener executes, call getValue() on the "value" ValueExpression. Pass the result to a call to setValue() on the "target" ValueExpression

This tag creates no output to the page currently being created. It is used solely for the side effect of ActionListener creation.
