Hello everyone, I'm new to Odoo. I am creating a module with a mechanism similar to odoo's project module. When I create a stage for a project, I declare the stage field as Many2One so that users can add stages without limitation. However, when I try to attach widget ="statusbar" to the stage view and run odoo, I always get the following error

Uncaught Promise > An error occurred in the owl lifecycle (see this Error's "cause" property)

Why does this happen? If I use fields.Selection the statusbar works fine but Many2One doesn't.

I appreciate your response, sir. However, I can see that the Odoo project module has a field called stage_id, and it has the value Many2One. They have also successfully applied widget="statusbar" to it.  Do you know how Odoo modified or configured the  Many2One field in order to use the statusbar ?

Hi,

The widget statusbar is developed to work with Selection fields rather than Many2one, but , as mentioned in the project module you can check the stage_id is the many2one field with comodel "project.task.type", similarly you will have to create a model for stages in the task


Thanks
