Code or Script File

You use the code file to define your component's attributes and actions. The attributes are called instance variables, and the actions are called methods. Files containing your code can be found in Project Builder's Classes suitcase, as previously discussed.

Your component code contains action methods. An action method is a method you associate with a user action-for instance, clicking a submit button or a hyperlink. There are two types of action methods you can implement: those for component action requests and those for direct action requests.

Elements bound to a component action pass the action message to the session object and on to the request component. State is restored by the session object.
Elements bound to a direct action send their action message directly to the object that can handle it. Direct actions aren't required to use session objects and thus can be stateless.

Your components can contain a mix of direct and component actions.

For a more detailed discussion of action methods, see "Action Methods".
