Jeff Pae-Corr commented on HHH-2667:
------------------------------------

I have confirmed the versions stated in the original entry are correct. The ablility to auto join collections works as expected in  3.1.3, 3.2.0 and 3.2.2 and It doesn't work with versions 3.2.3 and with 3.2.4.sp1. I have also tested this with 3.2.1 which is the version I used prior to updating to 3.2.3 and it funcitoned the way it should.

>             Project: Hibernate3
>          Issue Type: Bug
>    Affects Versions: 3.2.3, 3.2.4, 3.2.4.sp1
>         Environment: I have found that behaviour in version 3.2.4.sp1 and 3.2.3 (I didn't test 3.2.4 pre sp1)
> Database: ORACLE 10g
>            Reporter: Martin Kouba

> After upgrading to the latest Hibernate version I got this error.
> I try to use a statement like this
> from cat c where c.mate.id = 13
> the expected resulting SQL should be something like
> SELECT * FROM CAT C WHERE C.MATE_ID = 13
> which is much more performant than making a join
> from cat c join c.mate m where m.id = 13
> which would result in something like that
> SELECT * FROM CAT C INNER JOIN MATE M ON C.MATE_ID = M.ID WHERE M.ID = 13
> This works as expected in 3.1.3, 3.2.0 and 3.2.2
> It doesn't work with version 3.2.3 and with 3.2.4.sp1.
