Comment (by Thierry Bastian):
Thank you for your detailed answer. Your explanation makes perfect sense.
As you can imaging, I was trying to reproduce with the smallest possible
example. It might be that some detail made it work by chance. In the
original code, I am using .values, so the order of fields does not matter
that much and I reorganised them I the order *fields, *annotations.
That will probably work for me. I do hope that I don't have other places
where this fails silently ;).
thanks again.
