Description

using the example here https://www.northrivergeographic.com/archives/qgis-3-2-drive-down-lists-aka-value-relation-widget
with filter expression:

“fk” = current_value(‘type’)

the drive down list is correct, according type and subtype auxiliary tables.

but when the user submits a new feature to the point layer, the results in table are allways the same (the first subtype), like this:

fid type subtype
1 1 1
2 1 1
3 2 1
4 2 1
5 2 1
X X 1
