Modifying an Existing Controller
In version 4.0.3-1 of the Widget Framework , most of the controller functionality has been moved to Java. However, the framework still supports JSP controllers. These controllers are invoked after the Java controller has read the general and view-specific fields from the relevant panels in the widget and put them in the map (the map, in turn, is available in request scope). This means that JSP controllers can still be used to execute any custom logic.
