Description
Some expresssions can't be used in the refactor fields algorithm. The preview in the expression editor works fine, but the resulting field in the output remains empty.
Example of expressions that don't work:
represent_value("some_field")
relation_aggregates:
--Anzahl Sonden. Feld anz_sonden relation_aggregate( relation:='Erdwärmesonden', aggregate:='sum', expression:="anzahl_sonden" ) --Kumulierte Bohrlänge. Feld gesamt_bohrlaenge relation_aggregate( relation:='Erdwärmesonden', aggregate:='sum', expression:="anzahl_sonden" * "bohrtiefe" )
