Hi...

I have this class: A, B and C...
B and C extends the A class...

If i create a criteria to get A, i get A, B and C instances... i need only A, how i can to do this?

I'd also like to know. ......

the only solution I know of is to create a non persistent class, X

and let A, B and C extend X.

but that isn't preferable....

I'm not sure, but I think this might work:

criteria.Add(Restriction.Eq("class", typeof(A))

or if System.Type is not allowed typeof(A).FullName
