Bug introduced in https://github.com/odoo/odoo/commit/c8601f4384e0c95abc92d1f0b3092cfe2cb2a79d Purpose ======= If a module installation is supposed to load an action (example: a wizard like in l10n_eu_service) and if the related action is defined in this module (example: l10n_eu_service.wizard), currently we're using the environment defined on self, which is not updated after the module install, and the key is not defined in the registry. Specification ============= Instead of using the environment on self, let's use the new environment created after the cursor commit.
