public abstract class AjaxOnKeyPausedUpdater
extends org.apache.wicket.ajax.form.AjaxFormComponentUpdatingBehavior

Attaches itself to the onchange event for a TextField or TextArea, and enhances that event to fire not just when focus changes but also when keyboard input pauses. This is effected in JavaScript, with a timer that resets when the onkeyup event fires.
