My dao supports paging and sorting:

criteria.setFirstResult(firstRow);
criteria.setMaxResults(rowCount);
criteria.addOrder(sortAscending ? Order.desc(sortField) : Order.asc(sortField));

The object that I have has a one-to-many relationship and I'd like to support sorting on one of those columns. What sortField do I pass?

I don't know if this is a common solution, but I think this one works:
I added a createAlias to the related object so I can pass a field like "related.fieldName"
