| I have two simple joined entities and next exception when I try to get their property: Hibernate:
select
tarifklsk0_.ID as ID1_12_0_,
tarifklsk0_.FK_TARIF as FK_TARIF2_12_0_,
tarifservp1_.FK_TARIF as FK_TARIF2_11_1_,
tarifservp1_.ID as ID1_11_1_,
tarifservp1_.ID as ID1_11_2_,
tarifservp1_.FK_TARIF as FK_TARIF2_11_2_,
tarifservp1_.N1 as N3_11_2_
from
TR.TARIFXKLSK tarifklsk0_
left outer join
TR.TARIF_SERV_PROP tarifservp1_
on tarifklsk0_.FK_TARIF=tarifservp1_.FK_TARIF
where
tarifklsk0_.ID=?
