Duplicate features: attribute values with boolean data types are not duplicated correctly

Original Redmine Issue: 18687
Affected QGIS version: 3.1(master)
Redmine category:editing

---

When "duplicating features with digitize", the attribute values of boolean values as "true" are not correctly duplicated and result in a value of "false".

Can be reproduced when duplicating a "Anlage" feature in the Kanton Zug Erdwärmesondenprojekt where the original feature has the values set to "true" in the group "Geologische Begleitung und Raport" (see red frame in attached screenshot).

I tried to replicate with a smaller example - but failed.

Perhaps there is something special in our project configuration.

Do you think that the widget configuration has an influence on the duplicate process? We use a "Value map" as the widget for our boolean data to show "Ja/Nein" instead of "t" and "f".

Found out that this has nothing to do with "boolean" data types, but rather the fact that these attributes had default values assigned. Rather than copying the values from the existing partent feature, QGIS generated a new default value. This maske sense for some attribute fields, but not for all.

This issue will be closed, but most likely we will add a new feature request adding a third type of default value:

• normal default
• default also on updates
• default also for duplicated features
