Lesson Aim

In a Web application, there is often a need to respond to a user interaction or other events. This lesson covers events for UI components. JSF enables you to define actions that take place when certain events occur, such as when a page loads or when the user clicks a button. Events may trigger a change in the user interface, invoke back-end application code, or both.
