Bug 147530 [DataBinding] Provide event objects for change listeners
Before data binding goes 1.0 it would be wise to provide EventObjects for the following listeners to ensure that the API doesn't preclude future expansion of the values supplied to listeners. Interfaces that would be affected: * IValueChangeListener * IValueChangingListener * IListChangeListener * ISetChangeListener * IMappingChangeListener

private String value;
		private PropertyChangeSupport propertyChangeSupport;
		public Model(String value) {
			this.value = value;
			propertyChangeSupport = new PropertyChangeSupport(this);
		}
		public void addPropertyChangeListener(PropertyChangeListener listener) {
			propertyChangeSupport.addPropertyChangeListener(listener);
		}
		/**
		 * @return Returns the value.
		 */
		public String getValue() {
			return value;
		}
		/**
		 * @param value
		 *            The value to set.
		 */
		public void setValue(String value) {
			propertyChangeSupport.firePropertyChange("value", this.value,
					this.value = value);
		}
