Hello together,
in a line/polygon layer I want to merge two adjacent features. The geometries
are in a PostgreSQL table and / or in a Geopackage table. There exists an
auto-increment primary key field "id". In the QGIS "Identify feature", the "id"
field should not be displayed to QGIS users. In the layer properties the
"Widget Type" is set to "hidden" for this purpose. If I now merge both
features, the feature is immediately deleted after saving in the PostgreSQL
table without prompting! However, if I merge the features in the geopackage
table, the saving fails with the following error message:
Could not commit changes to layer "test_area (gpkg)"
Errors: ERROR: one geometry not changed.
Provider errors:
OGR error changing geometry: feature 0 not found
If I change the "Widget Type" back to "Range" the merging works fine
(PostgreSQL + Geopackage). Especially the behavior with PostgreSQL tables is
not really acceptable. This behavior occurs with QGIS 3.22.12/13 and 3.28.1 (OS
Version Windows 10 and Ubuntu 20.04). For my tests I used a new QGIS profile.
Before I write a bug report, I would like to ask here if someone has similar
problems or knows a solution.
Regards
Burghardt
