Bug report #20142

Numeric calculation in "Merge selected features" dialog does not work

Added by Harrissou Santanna over 5 years ago. Updated over 5 years ago.

Affected QGIS version:3.3(master) Regression?:Yes
Operating System: Easy fix?:No
Pull Request or Patch supplied:No Resolution:worksforme
Crashes QGIS or corrupts data:Yes Copied to github as #:27963


Select two features and click on "merge selected features" button
In the new dialog, for a numeric field try to use statistics functions like sum, count or whatever. The field in the "Merge" row becomes empty. If you try some statistics on a literal field you get the result in the field.
It's not simply a display issue given that if you do the merge, you get 0 in the numeric field.
I check "data corruption" as this is a tool that applies in-place modification and gives a wrong value you can not easily check later on/or rebuild.

Please try on QGIS 3.4.1, if the issue is still valid change the affected version, thanks.
