im trying to correctly map 2 classes: PropostaOrdine and Ordine
Ordine is a component of PropostaOrdine (the relation between the 2 obj is one-to-one)
*LOY_RIC_ORDINE (class: PropostaOrdine)
C_CMP (PK)(FK)
N_PRG_RIC_ORD(PK)
C_COD_ORD(FK)
*LOY_ORDINE (class: Ordine)
C_CMP (PK)
C_COD_ORD(PK)
when hib queries the db for instantiating a PropostaOrdine obj it
assigns values to its properties too; as one of PropostaOrdine’s properties
happens to be another java obj (Ordine in this case) i expect it to create an Ordine obj, asssign values to Ordine’s properties and assign that obj to PropostaOrdine
(hope my description is clear .. sorry for my bad english)
but that doesn’t happen .. so im trying to fix it and figure out more about hib mappings
any help will be greatly appreciated :D

Name and version of the database you are using:
oracle
The generated SQL (show_sql=true):
select propostaor0_.C_CMP as C_CMP,
propostaor0_.N_PRG_RIC_ORD as N_PRG_RI2_,
propostaor0_.C_STA_RIC as C_STA_RIC,
propostaor0_.C_TIP_ORD as C_TIP_ORD,
propostaor0_.C_COD_ORD as C_COD_ORD,
propostaor0_.cmp as cmp, propostaor0_.codOrd as codOrd
from LOY_RIC_ORDINE propostaor0_
where (propostaor0_.C_CMP=? ) and (propostaor0_.N_PRG_RIC_ORD=? )
shouldnt it be a join query with LOY_RIC_ORDINE and LOY_ORDINE ?
