You need to use a Many2many field to solve the relationship because Many2many fields does not need an inverse field. This is happening since I start using Odoo(OpenERP 6.0.3) and the concept has not changed


The one2many field is essentially the inverse relation corresponding to a many2one field.

As the error message says, you cannot have a many2one from a Model to a TransientModel, but you can have a many2one from a TransientModel to a TransientModel. So you can have a one2many in a TransientModel, as long as the comodel of that field is also a TransientModel.
