Summary

Tag name: <s:valueChangeNotifier>
Tag class: org.apache.myfaces.custom.valueChangeNotifier.ValueChangeNotifierTag

ValueChangeNotifier

Like valueChangeListener, but will send valueChange events after the UPDATE_MODEL phase.
This simply means you CAN update your model values within such an event now.
  • It wont be overwritten by the model update
  • And wont trigger another valueChange if you update a value with an valueChangeListener attached
