Hibernate version:3.0.5
Hi im migrating from hibernate 2 to hibernate 3 and several of the hql that where working are not working any more
for example the execute of this query:

select opp from org.volsystems.db.Opportunity as opp
inner join fetch opp.organization
, opp.volunteerCenter as vc
where opp.statusOpportunity.id = org.volsystems.db.StatusOpportunity.ACTIVE and vc.id = :vcId and ( ( opp.onGoing = true and vc.enableNewestLongTermOpportunity = true ) or ( opp.onGoing = false and vc.enableNewestOneTimeOpportunity = true ) ) and opp.endDate >= :dateParam and opp.activity = :isActivity order by opp.createdDate desc, opp.startDate asc



throws the exception

The exception says that opp.volunteerCenter is not mapped but i check and is maped , and is an very old query that worked fine with hiber 2

i set this
<property name="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</property>

to the hibernate.cfg.xml

to remove the ast and use the old parser and all the querys seem to work fine again, but i removed to try to find the error, and the only way i could make the query run with the ast hql parser was
changing this

select opp from org.volsystems.db.Opportunity as opp
inner join fetch opp.organization
, opp.volunteerCenter as vc ...

for this

select opp from org.volsystems.db.Opportunity as opp
inner join fetch opp.organization
inner join opp.volunteerCenter as vc ...

as you can see i remove the implicit join and it work , to confirm i changed that to others querys and it worked too, the problem is that im migrating a large application and ill have to change all the hql that use implicit joins with will be a lot of work, i supose i will have to use the old hql parser, but i wanted to use all the new cool features of the ast hql parser. So it is a bug? if it is do you have a fix in the cvs or something, or maybe you deprecate implicit joins of the ast parser.

Please help me.
