Chapter 8

Using Converters, Listeners and Validators

The previous chapter described different types of 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 in this chapter:
