Supporting Offline Mode in List Screenlets

A list Screenlet is a special type of read Screenlet that displays entities in a list. Recall from the list Screenlet creation tutorial that list Screenlets have a model class that encapsulates entities retrieved from the server. To support offline mode, a list Screenlet’s event class must extend ListEvent with the model class as a type argument. This event class also needs three things:

1. A default constructor
2. A getListKey method that returns a unique ID to store the entity with
3. A getModel method that returns the model instance

The list Screenlet creation tutorial contains example model and event classes that support offline mode for Bookmark List Screenlet. Click the following links to see the sections in the tutorial that show you how to create these classes:
