From this link: https://www.odoo.com/blog/odoo-news-5/post/odoo-8-release-notes-186. Warehouse management is rewritten and I also notice that stock_workflow.xml is not available in odoo 8 (the stock module doesn't have a workflow).

so how can I do some actions without that workflow?

ok, I just call the functions on the View (Python) mark this as correct pls
