> HQL query fails to navigate the associated collection. I have a Student <> Teacher many-to-many relationship and when I ask "select Student from Teacher t, t.Students where t.Name = :teacherName". This kind of query worked in NHibernate 2.0.1 GA.
> I tried it with NHibernate 3.1 an 3.2Beta1, which both gave the errror t.Students not mapped.
> NHibernate.Hql.Ast.ANTLR.QuerySyntaxException was unhandled
> Message=t.Students is not mapped [select Student from Teacher t, t.Students where t.Name = :teacherName]
> Source=NHibernate
> QueryString=select Student from Teacher t, t.Students where t.Name = :teacherName
