Description

When features are deleted from shapefile, in the Attribute Table not only the corresponding rows are removed but also other rows temporarily disappear.

Step to replicate the issue:
- create a new shapefile (the issue doesn't occur with other data formats)
- start editing and add two features: the first one with id=1 and the second one with id=2 (the insertion order is important)
- save editing (without this step the issue doesn't occur)
- open the Attribute Table
- select and delete the first inserted feature: the row with id=1 disappears as expected
- save editing: unexpectedly also the other row with id=2 disappears
- close and reopen the Attribute Table: the row with id=2 reappears

In general the issue occurs deleting features that have other features inserted after them.
The issue is OS independent, it occurs both in QGIS 2.14.21 and QGIS 2.18.17 but it doesn't occur in QGIS 2.8.9 (regression) and QGIS 3.0.0.

History

#1 Updated by Geo Dev over 6 years ago

More useful details using any shapefile:
deleting the first N features and saving the editing, in the attribute table exactly 2*N rows disappear.
N rows are correctly the features selected but the other N rows should not disappear.

#2 Updated by Geo Dev over 6 years ago

The issue still occurs in the last LTR.
The affected QGIS version can be updated to 2.18.20.

#3 Updated by Geo Dev about 6 years ago

The issue still occurs in QGIS 2.18.25.
It's a misleading issue since the user has the perception that more features than expected are deleted.

#4 Updated by Giovanni Manghi about 6 years ago

Affected QGIS version changed from 2.18.17 to 2.18.24

#5 Updated by Jürgen Fischer almost 6 years ago

Status changed from Open to Feedback

Please test with QGIS 3.4 - QGIS 2.18 reached it's end of life.

#6 Updated by Geo Dev almost 6 years ago

Status changed from Feedback to Open

The issue also occurs with QGIS 3.4.4 and QGIS 3.5(master) but with a different behavior.

Now the following error appears:

Commit errors: Could not commit changes to layer <layername>
Errors: ERROR: 1 feature(s) not deleted.
Provider errors:
OGR error deleting feature 1:

The steps to replicate the issue with QGIS 3.4.4 and QGIS 3.5(master) are slightly different:

- create a new shapefile (the issue doesn't occur with other data formats)
- start editing and add two features: the first one with id=1 and the second one with id=2 (the insertion order is important)
- save editing (without this step the issue doesn't occur)
- open the Attribute Table
- if the Attribute Table is not opened as docked window, dock it clicking on the button "Dock Attribute Table"
- select and delete the first feature inserted with id=1
- save editing
- select and delete the second feature inserted with id=2
- save editing: the OGR error appears

The issue doesn't occur if the Attribute Table is not docked or it's already open when the first "save editing" is done (third step).
