The only difference between version and my way is that version is not dependent on the object/row version but if a object is changed and saved it would't go from version 5 to 6 but it would look what has the last object changed version and increment it by 1 so it could be from 5 to 17.
Yeah its kind of an discrimator that I can sort on when makes my reqiest, can I have that even if I use joined subclasses?
