public class DBActorController
extends ActorController

A controller for database reference actors. They are rendered with a green box. Additionally, when the user right clicks on the composite actor, a menu item is added to the context menu that allows opening the referenced model for editing. Changes made with the actor opened from the database can be propagated to all other parents that include it by reference. If modifications are only made from the instance that is opened, the changes are not saved. This preserves data integrity.
