I have a problem in the Function Python for updating the destination location of selected lines in a Delivery order.

This is my javascript for selecting lines (in the JS, i call the function update_locations()) :

openerp.web_one2many_selectable = function(instance, m) 

var _t = instance.web._t,
 _lt = instance.web._lt;
QWeb = instance.web.qweb;

instance.web.form.widgets = instance.web.form.widgets.extend(

 'one2many_selectable' : 'instance.web.form.One2ManySelectable',
);

instance.web.form.One2ManySelectable = 
instance.web.form.FieldOne2Many.extend(

 multi_selection: true,
 start: function() 
 
 this._super.apply(this, arguments);
 var self=this;
 self.on("change:effective_readonly", this, function()
 if(this.get("effective_readonly"))
 self.$(".ep_button_confirm").attr("disabled", "");
 else
 self.$(".ep_button_confirm").removeAttr("disabled", "");
 );
 this.$el.prepend(QWeb.render("One2ManySelectable", widget: this));
 this.$el.find(".ep_button_confirm").click(function()
 self.action_selected_lines();
 );
 ,

 action_selected_lines: function()
 
 var self=this;
 selected_ids=self.get_selected_ids_one2many();

 var model_obj=new instance.web.Model("stock.picking");
 model_obj.call('update_locations',
 [selected_ids],context:self.dataset.context)
 .then(function(result)
 );

 ,
 get_selected_ids_one2many: function ()
 
 var ids =[];
 this.$el.find('th.oe_list_record_selector input:checked')
 .closest('tr').each(function () 
 ids.push(parseInt($(this).context.dataset.id));
 );
 return ids;
 ,
); 

And here is my Class Python (I think the problem is in the function update_locations() ) :

from openerp import models, fields, api


class stock_picking(models.Model):
_inherit = 'stock.picking'

new_location_dest_id = fields.Many2one(
 'stock.location', 'Destination Location',
 readonly=True,
 states=
 'draft': [('readonly', False)],
 'waiting': [('readonly', False)],
 'confirmed': [('readonly', False)],
 ,
 help="Location where the system will stock the finished products. This will be the default of the associated stock moves.")

@api.one
def update_locations(self):
 vals = 
 'location_dest_id': self.new_location_dest_id.id
 
 self.move_lines.write(vals)

When i select some lines and specify the location destination and click on the button for changing destination. a Message Error Appears :

Odoo MissingError One of the documents you are trying to access has been deleted, please try again after refreshing

i'm available for more informations, Thank you for your help guys.

I think that you do not need javascript, just a small module with a wizard, written using python and xml only. In the source code of Odoo itself you have a lot of them as examples, just look for the model used, models.TransientModel.
