Description
It seems to me that the correct behaviour here is to compute a distinct uuid for each feature.
A work around is to define a custom function like this
@from qgis.core import *
from qgis.gui import *
import uuid
@qgsfunction(args='auto', group='Custom')
def getUUID(feature, parent):
return '{' + str(uuid.uuid4()) + '}'@Associated revisions
Fix uuid() function returns the same uuid
Fixes #18130
