Summary
Tag name: <f:valueChangeListener>
Tag class: org.apache.myfaces.taglib.core.ValueChangeListenerTag
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.
