rafael liu santos commented on HHH-2081:
----------------------------------------

Doesn't ResultTransformer just maps the result to a bean?
I was thinking something like:

select a.bithday, catsons(a.name)
from animal a
where a1.parent = someparent
group by a1.birthday

And then we would implement a class "catson" that recives a list of  "a.name"s and return a concataned string of all names.
