Expand description

A generic interface for editors, implemented on controllers.

Provides all information necessary to execute actions, select objects, navigate and update. This makes it possible to write reusable generic actions.

Methods that returns Result can trigger a rollback in actions. This is to prevent logical errors from affecting data. Concurrent actions are not permitted at the same time.

View information must be stored internally in the editor. If the editor state depends on the view state, then it should not be updated before refresh_views is called.
