Chapter 8. Using Converters, Listeners, and Validators
The previous chapter described components and explained how to add them to a web page. This chapter provides information on adding more functionality to the components through converters, listeners, and validators.
• Converters are used to convert data that is received from the input components.
• Listeners are used to listen to the events happening in the page and perform actions as defined.
• Validators are used to validate the data that is received from the input components.
The following topics are addressed here:
• “Using the Standard Converters” on page 145
• “Registering Listeners on Components” on page 151
• “Using the Standard Validators” on page 152
