Original Redmine Issue: 20032
Affected QGIS version: 3.3(master)
Redmine category:forms

Using Geopackage setting 'Attributes form' to Text Edit Default value using $area and apply default value on update.
I get following result for different field types and for different versions

Int and Int64 gives failure

Version3.3 2aef195
If the field is an Int it gives NULL
If the field is decimal it gives eg. 5838,240008868463
If the field is an Int64 it gives 5838240008868463 same numbers but no decimal or round

Version 3.2 9b17680
If the field is an Int it gives 5838240008868463 same numbers but no decimal or round
If the field is decimal it gives eg. 5838,240008868463
If the field is an Int64 it gives NULL

When setting the Attributes form
Int64 and Decimal start as Text Edit and Int as Range

For me on linux an Int64 returns null.
Why this was tagged a regression, works fine on 2.18?

Regression from 3.2 to 3.3 sorry If I have misunderstood that ...

Hi Lene,
that is correct, is a regression. When is the case indicating since what version regressed helps us find the exact moment (in code) when the regression happened.

Anyway here on master (linux) if the field is an Int64 it gives NULL, so no difference with 3.2 (still a bug anyway).

I cannot reproduce on current master (or I didn't understand how to)

What are:

• the CRS
• the ellipsoid

Also, what are the area from measurement tools or postgis/spatialite st_area functions?

Can you send the geometry and maybe the project?
