Hi Frederick Thanks for answer.
I'm just trying to investigate why it is not chained whole over all associations. I think that each association shuold act as maybe proxy and pass from begining Shop.find(1) till the end of this chainings and pass Shop record. It sounds to me naturally way of living this kind of chainging. But I is it is not. I'm just guessing but I think this kind of behaviour is in DataMapper, am I right?
