@yvaucher well spotted, you're right. That method needs to be adapted then, let's talk about it when you want. Thanks!

[yvaucher]

Should certainly be a TransientModel

[lepistone]

Fixed as suggested by @yvaucher and rebased.

[lepistone]

I checked "functional testing". More testing would help for sure, but I think we can merge it.

[yvaucher]

@lepistone can you rebase to relaunch travis ?

[lepistone]

We're 💚 🍏
