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.
