Which model doesn't have an id field? If it has an pk or uid or some other name you should just let Cake know via the attribute $primaryKey. The join-table can manage without any primary key as long as you don't store any extra data in it. But this is not encouraged, it seems to be considered as smart as smoking cigarettes and drinking lighter-fluid at the same time. (I tried to discuss the point a while back.)
But, since you mention a position value in the joining table you do need an id there to make Cake happy.
