New State in Openerp7 - openerp-7

Question

... In openerp7
I want my new state to show up in sale module ... But it is not appearing
Pls have a look at code below
In sale.py module I added state like:
class Sale_order(osv.Model):
_inherit = 'sale.order'
_columns = {
'state': fields.selection([
('draft', 'Draft Quotation'),
('my_new_state', 'My New State'),
('sent', 'Quotation Sent'),
('cancel', 'Cancelled'),
('waiting_date', 'Waiting Schedule'),
('progress', 'Sales Order'),
('manual', 'Sale to Invoice'),
('invoice_except', 'Invoice Exception'),
('done', 'Done'),
], 'Status', readonly=True, track_visibility='onchange',
help="Gives the status of the quotation or sales order. \nThe exception status is automatically set when a cancel operation occurs in the processing of a document linked to the sales order. \nThe 'Waiting Schedule' status is set when the invoice is confirmed but waiting for the scheduler to run on the order date.", select=True),
}
And in sale_view.xml, I added this piece of code..
<openerp>
<data>
<!-- Inherit the sale order model's form view and customize -->
<record id="sale_form_view" model="ir.ui.view">
<field name="name">sale.order.form.inherit</field>
<field name="model">sale.order</field>
<field name="inherit_id" ref="sale.view_order_form"/>
<field name="arch" type="xml">
<!-- Statusbar widget should also contain the new status -->
<field name="state" position="replace">
<field name="state" widget="statusbar" statusbar_visible="draft,my_new_state,sent,invoiced,done" statusbar_colors='{"invoice_except":"red","waiting_date":"blue"}'/>
</field>
</field>
</record>
</data>
But.... My new state is not appearing between draft quotation and quotation sent
Please guide
Why is this so
Thanks

Answer 1

First thing I would check is to make sure you are replacing the proper field in your view (if there are several instances of a field named "state" in the view you inherit, the wrong occurence could be replaced). Check the view by opening the 'Modify FormView' item in the developper tools/view.
If it is the wrong occurence you are replacing, you main need to change your view definition by using an xpath expression.
Second thing I would check, is make sure the sequence of your inherited view is smaller that the original view you are trying to replace/modify. You can check in 'Manage Views' item in the developper tools/view.
Third thing I would try is to rename your class from 'Sale_order' to 'sale_order' just to match the name of the original class your are trying to override.
Hope this helps.
