Did anybody already have experience in implementing an undo/redo functionality with Yii?
My approach would be to use action-classes and keep their objects after executing run() persistent in the database. So I struggle with several open points:
How to persist objects from action-classes?
How to reduce effort in the database design due to a lot of different action-classes (ORM)?
How to make all persistent objects accessible - I guess I need a new model here?
How to call undo() in the right order - during a new controller?
Any help would be appreciated
