Nicolas De Cubber commented on HHH-2647:
----------------------------------------

I do not see the problem.
If i replace your query filters by letters (A,B,C...)
i will have :
[3/16/08 1:43:29:957 EDT] 00000032 SystemOut O from QueueCustomerView where (A and (B) and ( not ( not (C and D) and not (E and F) and not (G and D) and not (H and I))) order by customerStatusId desc , reassessmentDate asc 

and
3/16/08 1:43:29:973 EDT] 00000032 SystemOut O Hibernate: select ... from kycr.vw_customer_queue queuecusto0_ where (A and (B) and (C and D or E and F or G and D or H and I) order by queuecusto0_.CUST_IS_NEW desc, queuecusto0_.REASS_DT asc 

which the where condition can be write has follow :
A.B. !( !(C.D).!(E.F).!(G.D).!(H.I))
which can be rewriten has follow:
A.B. (  !!(C.D)+!!(E.F)+!!(G.D)+!!(H.I))
or has follow:
A.B.( (C.D)+(E.F)+(G.D)+(H.I))

but, because '.' has prioritary on '+', you could also write it like :
A.B.(C.D+E.F+G.D+H.I) which is what is given by hibernate, so there is no problem, in my point of view.
