Description

User Feedback

QGIS crashed when I tried to delete a virtual field from a shapefile.

I experienced two other issues with virtual fields in the same project session, not sure if they're related or not but I include details on those issues in case its helpful.

I added the virtual field when the shapefile was in edit mode. Every time I tried to save edits made to the shapefile, it gave an error along the lines of "unexpected number of fields, expecting 4 fields but found 5" (not exact quote).

In the same project session, I added a second virtual field to another shapefile. This virtual field used intersecting_geom_sum() function (from refFunctions plugin) to add up values of the first virtual field. This second virtual field worked correctly for existing features, but when I added new features they had null values in this field, even after saving edits.

History

#1 Updated by Nathan Perry about 2 years ago

Same issue here, QGIS 3.0.2 running in Mac OS 10.13.3. I have both the "too many attributes" error and the crash when deleting the virtual field.

#2 Updated by Antoine Lafranchis about 2 years ago

Steps to reproduce this issue in version 3.0.3:
  1. Create new project, without saving it
  2. Create temporary scratch layer with no geometry
  3. Add 6 new features
  4. Toggle edit mode off and save changes
  5. Open attribute table and field calculator
  6. Add virtual field with type integer, name test1 and expression 1
  7. Add virtual field with type integer, name test2 and expression 2
  8. Toggle edit mode on with the button in the attribute table
  9. Click the delete field button in the attribute table
  10. Select the two virtual fields and click OK

#3 Updated by Matthew Bodnar about 2 years ago

I have encountered this crash behavior on 3.03 when attempting to remove a virtual field from a layer table in a geopackage. I was able to remove one of 3 virtual fields, save edits and the crash was encountered upon trying to delete the seconf virtual field. There was no error statement prior to crash. Crash handler log below..

Update...

I am able to remove only (1) virtual field per session. To delete more I must save edits and restart QGIS completely.
