Hi all,

I have an entity that has a collection in it. The collection is a OneToMany unidirectional relationship storing who viewed a particular file. The problem I am having is that after I load the entity and try to update the collection, I don't get any errors, but the collection is never updated:

Entity:

@OneToMany(cascade = CascadeType.PERSIST)
@JoinTable
protected List<User> users;

File Servlet

@In
private EntityQuery<File> File_findById;

...

File file = File_findById(fileId);
file.getUsers().add(user);
session.update(file);

Even though I call session.update(file) and I see stuff in hibernate logs, I don't see anything in the database indicating that it was saved.
