Hi pbreit, Thanks for your input, but that will not work, since row.fieldname still incorrectly returns the Set object (therefore not executing the 'or' statement).
Secondly, fieldname is a str variable in my case, which can't be used directly with the dot notation. I just need to not have these back references automatically added to the row dictionary, maybe via a new switch, if possible. Massimo, what do you think?. Thanks, Carlos
