After creating a new JavaBean and its EventListener and EventObject subclasses, it is possible to see the methods in the EventListener class by dropping an instance of the bean onto a JFrame in the IDE, then right-clicking on the bean in the Navigator, and choosing Events/<event name>. However, after closing the JFrame in the editor, opening the EventListener class, adding a new method to that class, saving it, and reopening the JFrame, right-clicking on the bean in the Navigator and choosing Events/<event name> does not show the newly added method. To see it, NetBeans must lose and regain the focus while the JFrame file is closed, or Source/Scan for External Changes must be chosen while the JFrame file is closed.

Saving changes to the EventListener for a JavaBean should cause rescanning automatically.
