Hi Laura,

Is it an idea to create an issue for it at:
https://github.com/qgis/QGIS/issues (you will need a github account).

Because then you are 'forced' to give some more information then you provide here :-)
Like: what version of QGIS are you using on what platform, and can you describe the process on how others should see this issue too (to reproduce this behaviour). For example: are we creating new features here?

This way interested people can either:
- confirm the issue (and then it is up to developers to fix it)
- or could find out why it is not working for you (and hopefully it is then working again).

If you are not willing/able to create an issue, then please provide the information here (QGIS-version and a clear set of steps to reproduce).

Regards,

Richard Duivenvoorde

But when I reopen the attribute form, the default value field shows the previous preview (e.g. 123456) value instead. So no new UUID is generated. I have the same problem even if I don’t set the command as a default value and only select the UUID generator as the widget type. I experience this Problem with every default value i set.
