Code review comment for lp:~alexis-via/openobject-addons/extensible-stock-action_invoice_create

The first attempt by Renato Lima (unfortunately, I was not aware of it) was rejected by Fabien "as it crashed the buildbot when installing stock_invoice_directly". I tested the installation of stock_invoice_directly with my merge proposal : it installs fine. I tested a sale order + delivery with this module : it crashes... but it also crashes with a standard addons/trunk, so it's not caused by the changes introduced in my merge proposal.
