Description

Drop-down list of Relation reference widget:

Whatever "Representation for NULL values" is configured in "Options - Data Sources", a NULL value in the drop-down list is always wrongly displayed as "NULL".

See attached example with "MY_NULL_REPRESENTATION_VALUE" as NULL representation.

does this also happen if you restart QGIS after changing the null value representation?

#2 Updated by Manuel K about 2 years ago

Yes.
I changed the null value representation to several other values (my preferred setting is an empty string by the way) and always restarted QGIS. Same behaviour.
