Hi, 

I'm new Odoo and I use Odoo 8.

I want to add a new state for my quotations between drafts and sends quotations.

But I just can't :(. 

My problems are i don't see my new state in status tab and in statusbar new state appear at last of selection.

My proceed: 

     - models.py:

         # -*- coding: utf-8 -*-

from openerp import models, fields, api

class SaleStates(models.Model):

    _inherit = 'sale.order'

    state = fields.Selection(selection_add=[('new_state', "New State Quotation")])

    @api.multi
    def new_state(self):
        self.state = 'new_state'

# SaleStates()

     - sale_order_workflow.xml:

<?xml version="1.0" encoding="utf-8"?>
<openerp>
    <data>
        <record id="act_quotation_approved" model="workflow.activity">

                    Odoo will help you handle efficiently the complete sale flow:
                    from the quotation to the sales order, the
                    delivery, the invoicing and the payment collection.
                </p>
                <p>
                    The social feature helps you organize discussions on each sales
                    order, and allow your customers to keep track of the evolution
                    of the sales order.
