> 'illegal attempt to dereference collection' when using auto-join

>                 Key: HHH-2667
>                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2667
>             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.
