I'm trying to visualize in the projects module the amount of the sales order/contract associated to that project. My code uses related fields and somehow I the fields show up with all their attributes from the sale order (ie help info) but they show up as empty.

Why do the fields show up correctly but not the actual values?

This is the field in the sale.order model:

from openerp import fields, models, api
class Sale(models.Model):       
      _inherit = 'sale.order'
      sale_order_project = fields.One2many('project.project', 'sale_order', string = 'Sale Order Project')

This is the related field in the project model:

from openerp import fields, models, api
class Project(models.Model):
        _inherit = 'project.project'
        sale_order = fields.Many2one('sale.order', string = 'Sale Order')
        amount_total_untaxed = fields.Float('Amount Untaxed', related = 'sale_order.amount_untaxed', store=True)
        amount_total = fields.Float('Amount Total', related='sale_order.amount_total',store = True)

Thanks!
