select elements(collection) does not return all composite key segments when used in subquery
--------------------------------------------------------------------------------------------

                 Key: HHH-3139
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3139
             Project: Hibernate3
          Issue Type: Bug
          Components: query-hql
    Affects Versions: 3.2.4
         Environment: HB 3, Oracle 10g
            Reporter: Carl Allain
            Priority: Blocker


When dealing with collection of entities having composite keys, elements() seems to return all key segment columns, which seems fine.

So, in our case (CountrySubdivision has a composite PK, :CTRSD_CD + CTR_ISO_CD), when we do

select elements(mks.countrySubdivisions) from MarketSegmentPdo mks

it gives this:

select
  countrysub1_.CTRSD_CD as col_0_0_,
  countrysub1_.CTR_ISO_CD as col_0_1_ 
 from
  MKSG_MKS marketsegm0_,
  MKSG_MKSCTRSD countrysub1_ 
 where
  marketsegm0_.MKS_NRI=countrysub1_.MKS_NRI

while using the same elements() function construct in a subquery, only one PK segment is included by Hibernate!. So:

from CountrySubdivisionPdo cs where cs.id in (select elements(mks.countrySubdivisions) from MarketSegmentPdo mks)

gives this:

select
  countrysub0_.CTRSD_CD as CTRSD1_65_,
  countrysub0_.CTR_ISO_CD as CTR2_65_,
  countrysub0_.CTRSD_TS as CTRSD3_65_ 
 from
  PLGE_CTRSD countrysub0_ 
 where
  (
   countrysub0_.CTRSD_CD, countrysub0_.CTR_ISO_CD
  ) in (
   select
    countrysub2_.CTRSD_CD <---------------------------------- WHERE is CTR_ISO_CD???????
   from
    MKSG_MKS marketsegm1_,
    MKSG_MKSCTRSD countrysub2_ 
   where
    marketsegm1_.MKS_NRI=countrysub2_.MKS_NRI
  )
