# API Enhancements to the JavaBeans Component API in Java SE 5.0

This document describes changes to the `java.beans` package that were introduced in Java SE 5.0:

- Support for IndexedPropertyChangeEvent
- New Method for Creating a PropertyEditor
- Public Constructors for PropertyEditorSupport

## Support for IndexedPropertyChangeEvent

The bugtraq report that corresponds to this change is: 4353056

A new subclass of `PropertyChangeEvent` named `IndexedPropertyChangeEvent` has been added to support bound properties that use an index to identify the part of the bean that changed. Also, three methods, all named `fireIndexedPropertyChange`, have been added to the `PropertyChangeSupport` utility class to support firing indexed property change events. You can find an example of using indexed property change events in `IndexedTest.java`.

## New Method for Creating a PropertyEditor

The bugtraq report that corresponds to this change is: 4274639

A new method called `createPropertyEditor` has been added to the `PropertyDescriptor` class.

## Public Constructors for PropertyEditorSupport

The bugtraq report that corresponds to this change is: 4305280

The two `PropertyEditorSupport` constructors are now public instead of protected, so that `PropertyEditorSupport` objects can be more easily created and used as delegates. Also, the source object is now exposed by means of new `setSource` and `getSource` methods.
