Code review comment for lp:~camptocamp/department-mgmt/7.0-port-sale_department

This issue doesn't seems to come from sale_department but from its dependency invoice_department which conflicts with portal_sale (auto installed with portal and sale thus with sale_department).

To complete install of sale_department from scratch I had to do those steps:

- comment invoice_form and invoice_supplier_form in invoice_department/invoice_view.xml
- comment invoice_form_payment in portal_sale/portal_sale_view.xml
- launch OpenERP with --update=all
- uncomment view in portal_sale
- launch OpenERP with --update=portal_sale
- uncomment view in invoice_department
- launch OpenERP with --update=invoice_department

I guess this is due to some OpenERP bug in view inheritance...
