extends javax.servlet.jsp.tagext.TagSupport

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
