Now, the ListControl is instanced within the UserBrowseAction and filled with the data to be displayed. To do so, using the setDataModel() method, its data model is assigned to the control element. The method setDataModel() takes up, as an argument, a ListDataModel. What is involved here is a simple interface, which is implemented by the class UserDisplayList, which provides the display data.
