JSF Core Facelets Tag Library.
Tag valueChangeListener
Adds the specified ValueChangeListener to the nearest parent UIComponent (which is expected to be a UIInput
component).
Whenever the form containing the parent UIComponent is submitted, an instance of the specified type is created. If
the submitted value from the component is different from the component's current value then a ValueChangeEvent is
queued. When the ValueChangeEvent is processed (at end of the validate phase for non-immediate components, or at end
of the apply-request-values phase for immediate components) the object's processValueChange method is invoked.
Unless otherwise specified, all attributes accept static values or EL expressions.
Register an ValueChangeListener instance on the UIComponent associated with the closest parent UIComponent custom
action.
See tag documentation.
