Comment 2 for bug 918288

In both case, I can notice that even the "Run procurement" button does nothing (and that's what the _procure_confirm method also does with "wf_service.trg_validate(uid, 'procurement.order', proc.id, 'button_check', cr)").

So it seems that it's related to a workflow missing step.
