Sebastian, I appreciate the try. But I needed an avg of a field and
considering that I don't know how to write it in plain sql either
without the avg being used in the result, I think it cannot be done
with Criteria either.

In that case, there is no other way.

You don't need projections for ordering just order on a field. if the
ordering takes place in a relation, then create an alias and use it in the
order condition.

I'm using tapestry-hibernate and I have a case where I'm forced to use
Projections (or aggregate functions in hql but same end result) so my
query is returning an object array. Now, I'm rendering a list of that
information to the user, but since using ${obj[0]} expansion is not
supported, I'm forced to write a getter for each synthetic property
(so I can refer to them with ${objProp1}, ${objProp2} etc.) I'm
displaying in my grid. It's not too bad, but is there a better way to
do this? (could do it with ognl, but I would like to avoid adding a
new dependency just for this).

PS. Bonus points if you tell me how to make Hibernate return objects
with Criteria api if I only need projections for ordering the result
set.
