Hello

I did a module to convert some picking product weight into some other product sell by pound

everything work fine, I did had the same kind of field to the picking and the pack_operation (maple_weight)

so when someone add to a pack_op a pack_ops_lot, the total weight of the pack_op is transert as qty_done of an other product in the same picking.  Everything work fine except qty on screen does get strange refresh.

The total weight of the picking and the pack_op update on screen after every change to pack_op_lot but the weight transfer to qty seam to show the previous state and not the last.

If I add a 415 pounds product, qty_done still show 0 and both total_weight show 415, if I add an other of 416 the both total show 831 and qty show 415.  If I remove from the lot the 415, totals goes down to 416 and qty goes up to 831.

Looking at the database, the qty_done is always good.

there is the most important part of the code

    @api.one
    @api.depends('pack_lot_ids')
    def _compute_pack_ops_weight(self):
       
        weight = 0
        if self.product_id.maple_container:
            for lot in self.pack_lot_ids:
                for quant in lot.lot_id.quant_ids:
                    weight += quant.maple_net_weight * lot.qty
            if self.picking_id:
                related_op = self.picking_id.pack_operation_ids.filtered(lambda r: r.product_id.default_code == self.product_id.default_code[1:] )
                if not related_op:
                    # faut créée un pack ops
                    ops_val = {
                        'date' : self.date,
                        }
               
                related_op.write({
                        'qty_done' : weight
                        })
                related_op.save()

        self.maple_weight= weight
