Sorry, those were typos. Customer is singular and there is no
comments database just a customers one. That is, comments should have
been customers. As noted, the program does work perfectly, except in
Rails and of course it couldn't possibly be a problem of ids because I
can get it to work in Rails as well but only if I use a two step
procedure. As noted, x = e.department and then x.customers.size
Therefore, it is not a problem of ids as it works in rails 2.3.5, it
just takes two steps but why two steps instead of one?
