JPA Container and scoped fields

Flow
1

Hi.
I’m trying the JPA Container with Hibernate.

Now I want to create a custom query with scope containing fields, like this:

select c.name, c.city.name, c.country.name from Customers as c

Is this possible with JPAContainer, without using the IndexedContainer?
I need to mantain the “lazy” fetch for the query.

I dont want to perform the query and add the results one-by-one, this is a heavy process.
