Description:
I'm switching to 2.0.1 from 1.2.3. I received the following error trying to do a query on a collection that's within a component. Obviously, this used to work in 1.2.3. I've included part of my mapping below. Using elements(mov.cast.cast.list) did not help.
net.sf.hibernate.QueryException: could not resolve property type: cast.cast.null [SELECT mov.id FROM mov in class Movie WHERE :findTarget in mov.component.list.elements]
