Hi,

I have a QBE query where I have an Offence Entity, that has a foreign key Entity called 'FleetVehicle'. The associations are setup correctly I believe.

The Offence POJO Entity contains a FleetVehicle POJO/Entity but when I reference fleetVehicle.registrationNumber (I expect the QBE to do the join for me...) it bails complaining that it cannot resolve the field registrationNumber in the Offence entity??

Hibernate version:2.1.7

Sorry, problem my end... I *was* referring to offence registrationNumber in the QBE at the top of the query.... but with that removed I still get an error:

{ERROR} actions.ViewAction Thread [http-8080-Processor4]; Error when loading offences [could not resolve property: fleetVehicle.registrationNumber of: com.ocado.tracker.offences.pojo.Offence; nested exception is net.sf.hibernate.QueryException: could not resolve property: fleetVehicle.registrationNumber of: com.ocado.tracker.offences.pojo.Offence]
org.springframework.orm.hibernate.HibernateQueryException: could not resolve property:

fleetVehicle.registrationNumber of: com.ocado.tracker.offences.pojo.Offence; nested exception is

Can you actually use entity.foreignEntity notation in QBE?

It seems to work nicely:

Offence is the parent and FleetVehicle my association:

Example exampleOffence = Example.create(offence)
.ignoreCase()
.enableLike(MatchMode.ANYWHERE);

Criteria criteria = session.createCriteria(Offence.class);

criteria.createCriteria("fleetVehicle").add(Expression.ilike("registrationNumber", "aregnumber", MatchMode.ANYWHERE));

return criteria.list();
