NH-2049 - Error with filters on joined-subclass as one-to-one

[nhibernate-bot]

We have following entities:

• Customer, which has deleted property
• IndividualCustomer, which is inherited from Customer and has one-to-one (mapped as many-to-one with unique=true) relation to Person
• Person which has IndividualCustomer property as one-to-one with property-ref to IndividualCustomer's Person property

If we enable filter, which filters deleted customers by deleted property and get person with criteria, following SQL is generated:

SELECT ...
FROM   Person this_
left outer join IndividualCustomer individual2_ on this_.Id = individual2_.PersonID and individual2_1_.Deleted = 1
left outer join Customer individual2_1_ on individual2_.IndividualCustomerID = individual2_1_.Id

This obviously fails because the "filtering condition" (individual21.Deleted = 1) is in wrong join.

Still happen in Hibernate 3.2.0.3001. Attaching a NHibernate 3.2 test fixture with a simplier exemple to reproduce.

Does anyone have a patch for this? I'd be willing to try it. This bug is stopping us from inserting data.

Note that NH2049.zip uses a criteria query, while NH2049-NHib-3.2RC1.zip uses HQL. Both fail. Combined and slightly reworked test cases, still failing, added to 3.4.x branch in 7240908.

Still happens on 5.3
