> Bernard Ligny is right by expected this behiavour :
> Extract of topic :
> " But this leads me to the following suggestion:
> I was wondering if, with the help of the not-null attribute in my <many-to-one> mapping, Hibernate could not smartly utilize such information in order to decide how to translate the implicit join:
> - if not-null="true" => translated into a normal join
> - if not-null="false" => translated into an outer join "
> I think than hibernate will better with this behiavour, for me this is bug to ignore the not-null information in association many-to-one to build SQL request.
> Of course is possible to write explictly the outer join, but is it realy the philosophy of hibernate ?
