Steps to reproduce

1. Install Ibexa DXP v4.5
2. Create a new content type with two text line fields, where one of them is non-translatable
3. Create content of newly created type
4. Edit the content and change both values
5. Save

Result

The field that is marked as non-translatable has reverted to its pre-save version

Expected Result

Both fields should have saved the value correctly

Note

The problem occurred after changes from https://issues.ibexa.co/browse/IBX-4031
