[QGIS-Developer] $geometry does not consider changes in the edit uffer

[Denis Rouzaud]

Hi Nyall,

Thanks for testing.

I tried again and still observe the issue.
I have found worst issues with setting this virtual fields with expression
"num_points( $geometry )"

- when adding a new feature and committing I get an error saying:
Feature has too many attributes (expecting 1, received 2)
although feature is correctly written to the provider

- the function seems to return actually 1 vertex more than there actually
is in the geometry

- I do need to commit to get the changes

I tested both with geopkg and shapefiles.
And I did not started alcohol yet today.

Cheers,
Denis
