28 * An "IndexedPropertyChange" event gets delivered whenever a component that
29 * conforms to the JavaBeans™ specification (a "bean") changes a bound

36 * An event source may send a null object as the name to indicate that an
37 * arbitrary set of if its properties have changed. In this case the
38 * old and new values should also be null.
