Hi Andreas, just a wild guess: Could it be related with the Umlaut "ä"

Hi, I use a relation_aggregate expression with the following syntax: relation_aggregate( relation:='Erdwärmesonden', aggregate:='sum',expression:="anzahl_sonden") In the output preview this works fine and I get an expected result, however, if I use the same expression in a virtual field, I always get NULL values. Any idea why this happens?
