public class PropertyChangeBridge
extends java.lang.Object
implements java.beans.PropertyChangeListener

Delegates property changes from an underlying bean to the BeanMetaObject that contains it. Reference to the bean meta-object is kept using a WeakReference and this object will removed from any event sources that it knows about when the reference is null. In other words, this listener will remove itself from the real beans when the bean meta-object goes away.
