Badge is not colored

Problem: The badge appears but without color.

Solution: Make sure the related model has the color field (or the field specified in color_field) and that it contains a non-zero integer value.

Widget not working after install

Problem: Module is installed but the widget has no effect.

Solution:

1. Clear browser cache (Ctrl+Shift+R)
2. Restart the Odoo server
3. Check the browser console for JavaScript errors

Color not saved after clicking

Solution: Ensure the user has write access to the related model (e.g. my.category), since the color is saved directly on the related record via orm.write.
