Hi Salvatore,
you are right: it seem the expression is not correctly evaluated in a
virtual field (using the Field Calculator with the "Create a new field" and
"Create virtual field" options both checked).

Hi Andrea,
I finally understood the mistake.
First you need to create the 'zona_fill2' field and then populate it with
the expression:
if ("zone" is empty,
attribute (get_feature_by_id (@layer, $ id -1),
'zona_fill2'), "area")
So the mistake I was making is

Hi Salvatore,
I've imported your csv file, copied the features to a new scratch memory
layer, and created a new field named 'zona_fill2' using the

Seems to me you are trying to calculate "zona" to "zona_fill". If that's
the case, you need to
