48 Chapter 2: Using Flash Remoting ActionScript

The ActionScript code for this example imports the Service, Log, RelayResponder, FaultEvent,

ResultEvent, PendingCall, and RecordSet classes for Flash Remoting. In addition, it imports the

appropriate classes for the user interface components. The application creates the

CustomerInfoForm class, which extends the Form class. The sections following the ActionScript

code describe the functions in this class.
