Spring Data JPA + querydsl: Create Predicate that includes join

[beginner_]

What I want is to be able to call findAll method with a predicate that filters by referenced entities.

basically exactly what was asked here over a year ago:

http://forum.springsource.org/showth...OneToMany-join

Is that possible at all?

Note:

I need these because I have a Boolean Expression which I can't express with standard JPA findBy... method. The actual filter (true or false) is a postgresql function call and not a simple like or eq or gt.

Yes, it's possible. Put an any() at the end of a collection path to get a single entry.
