Prefetching Question

If for example i have the following classes: Person, Hobbies and Hobby

Hobbies has fields:  personId and hobbyId

If no prefetching is done on the original Person query, is there a way to 
prefetch Hobby when calling getHobbies() on Person ?

Thanks.

Just flatten the join and simplify your code:
