"Merge selected features" tool and non spatial layer #43738

Open DelazJ opened 3 years ago

DelazJ commented 3 years ago

Given a geometryless layer, put it into edit mode and select two features In the Edit menu, the "Edit geometry --> Merge selected features" is available to use. Should it be? If yes, then I would suggest to move it out of the "Edit geometry" menu. Select the "Merge selected features" tool, fill in the dialog and apply. You get an error:

CRITICAL Merge failed : An error occurred during the merge operation.

So, either we disable the "Merge selected features" when a geometryless layer is selected or we make it work with them and move it in the menu

Can still confirm this on QGIS 3.16.14 and 3.22.1. Merge selected features is still enabled when editing a layer with no geometry, after trying to merge, the same error appears, as mentioned.
