Ali Ibrahim commented on HHH-1751:
----------------------------------

Ran into this problem too...

It seems pretty serious since the documentation implies that scroll and fetching should work. I worked around by manually collating the results, but it was pretty painful.

Same symptoms: only 1 of the *many* side of a *one-to-many* is fetched.
