Comment 6 for bug 1222867

Hi, yes I am working on it.
Two big change
- first I extract a generic module "exception_rule" in order to use exception in sale order, purchase order, and why not picking, invoice....
- secondly I change the check box 'ignore exception' by 2 button "cancel validation" and "ignore exception and force validation"

I think it's more user friendly than checking a box and validating it, what do you think?

You can try my branch if you want I will propose a merge this week
