I figured it out. I should have seen it immediately.

The calculation (the implementation of a python function) needs a
return. So it should be 
  return record.related["produca"]["comments"]
instead of just
  record.related["produca"]["comments"]

I'm not sure when python needs the return and when it just uses the
last-evaluated value. Maybe there is something that I can do to make it
work without the "return".

Also make sure that the field has the correct type: You will not get
good results if you used a numeric field for this example, for instance.
