Qgis 3.40 Copy/paste not working with attributes values

[alfernet]

What is the bug or the crash?

When copy and paste entities, records are well pasted but not the attribute values (whereas the attributes names are the same and field type are the same as well). Everything has a null value.

Steps to reproduce the issue

select entities, click copy entities, in the destination table, paste entities --> rows for the new entities are well created, attributes values are lost.

@alfernet, thanks for reporting. I cannot replicate the issue running QGIS 3.40.5 on Windows 10. Please provide sample QGIS project and layers and detailed step-by-step instruction in order to replicate the issue.

thanks for your reply. To be more precise it happens when I want to paste data in a postgis table, and the field is a pkey. It seams that it is now the right behavior of qgis : not possible to paste data in a pkey field ? Do you confirm this ? Many thanks in advance,

[agiudiceandrea]

@alfernet, didn't the issue occur using a previous version of QGIS? If it didn't, which version?

[alfernet]

@agiudiceandrea So far I was using 3.16.4 and it was working well with this version, I wanted to use the 3.40.4 and discovered the same process does not work. I then tried with the 3.38.3 and it does not work as well. I have not tried with other previous ltr thinking this was now the new way of QGIS. Here is a gif showing how I proceed.
I copy elements from a shapefile, to paste them in a postgis table. Same field name on both table, , destination field in the postgis table is a pkey. If the field is empty when saving, postgis will generate the values. On 3.16.4, I could paste values, the pasted values were saved.
