Hi,

I have a slight or should I say "major" problem.

I have an object A with a couple of properties but it also has an object B inside and Object B also has a couple of properties.

If I want to use the Criteria API I would use the A.class and ad an expression however since they mapped I would like to search for all the Objects A but based on a property in Object B.

If I use the Criteria API and I try the objectB.name for example but it gives me a "no such property" exception which is understandable since the property is in ObjectB but I still want to be able to search this way.
Is this possible ? If so how?

In my mappings I have a many-to-one to ObjectB from ObjectA...

Thanks

Nope,

Nothing in there has really helped my problem. Is there something special you need to do in the mapping? Its really an issue I cannot seem to sort out

So this didn't work?

Code:
List objectAs = session.createCriteria(A.class)
    .createCriteria("B")
        .add( Restrictions.eq("name", "name_i_want_from_b") )
    .list();
