The product configurator dialog was still in legacy code as it was not required for the migration of the views to OWL. Now that we're moving forward with the removal of other parts of the legacy code, this dialog had to be converted as well. Some parts of the logic have now been rewritten in OWL, getting a better share of the logic between the server and the client. The product configurator in e-commerce still uses the old implementation and will be refactored in another task. task-3056806 closes odoo/odoo#106511 Related: odoo/enterprise#39525 Related: odoo/upgrade#4550 Signed-off-by: Valentin Chevalier <vcr@odoo.com>
