Hello,

i porting/developing a module (working un V8).

It have a wizard , from the wizard we jump to a editable tree view with results and the option to confirm the operation.

I create the model (transient) en when clicking in the button (confirm the action) the data in the form get lost, all the fields cames empty

Here is my code:

the XML:

     product.prices_update_wizard_result
     product.prices_update_wizard_result
     
         
             

                 
             

             
         
     
  

 
     product.prices_update_wizard_result_detail.tree
     product.prices_update_wizard_result_detail
     
         
             
             
             
         
     
 

and the py file:

class prices_update_wizard_result_detail(models.TransientModel):
    _name = 'product.prices_update_wizard_result_detail'
    _description = "details results"

    result_id = fields.Many2one(
        'product.prices_update_wizard_result', 'Result')
    product_tmpl_id = fields.Many2one(
        'product.template', 'Product Template',
        readonly=True)
    old_price = fields.Float(
        'Old Price',
        readonly=True)
    new_price = fields.Float(
        'New Price',
        required=True
    )


class prices_update_wizard_result(models.TransientModel):
    _name = 'product.prices_update_wizard_result'
    _description = "results"

    @api.model
    def default_get(self, fields_list):
        res=super(prices_update_wizard_result,self).default_get(fields_list)
        ret = []
        price_discount = self._context.get('price_discount', 0.0)
        price_surcharge = self._context.get('price_surcharge', 0.0)
        price_round = self._context.get('price_round', 0.0)
        product_tmpl_ids = self._context.get('product_tmpl_ids', [])
        price_type = self._context.get('price_type', False)
        for product_tmpl in self.env['product.template'].browse(
                product_tmpl_ids):
            if price_type == 'list_price':
                old_price = product_tmpl.list_price
            elif price_type == 'standard_price':
                old_price = product_tmpl.standard_price
            else:
                raise UserError(_('Price type "%s" is not implemented') % (price_type))
            vals = {
                'product_tmpl_id': product_tmpl.id,
                'old_price': old_price,
                'new_price': self.env[
                    'product.prices_update_wizard'].calc_new_price(
                    old_price, price_discount,
                    price_surcharge, price_round),
            }
            ret.append([0,0,vals])
        res.update({'detail_ids':ret})
        return res


    detail_ids = fields.One2many(
        'product.prices_update_wizard_result_detail',
        'result_id',
        string='Products Detail',
        store=False,
             )

    def confirm(self):
        products_vals = []
        price_type = self._context.get('price_type', False)
        for line in self.detail_ids: #self.detail_ids comes empty
            vals = {
                'product_tmpl': line.product_tmpl_id,
                'new_price': line.new_price,
            }
            products_vals.append(vals)
        return self.env['product.prices_update_wizard'].update_prices(
            products_vals, price_type)

if i change to models.Model works, but, if i perform a inline editiong, don't get stored in the self.detail_ids

Try with force_save but not solved at all

Any idea of any posible solution?
