Jajajaja So funny the presentation, I just want think that OpenERP didn't F*~k nobody ;-) (I need to see again this movie). Some point at the end of the day, we need to give answers to everysingle document, because the many2one nightmare is there Fabien, Ok i can live with the new data structure, I can live with the new models stuff, but for Sure I think it is worng in terms of think all options, and the table shared by Raphael speak by itself. Lets say, this was what i was talking about before, no matter the solution we need to analize the impact in every object, because in some cases the contact is right in other ones the contact is totally incorrect. This remember me the problem with the invoice and the number, OpenERP design a new solution, "We use it" and it is working in our localizations. What will be this time friend? Because even in some cases will not be the "End Solution" just put the contact, even you will need to develop a configuration option, where (Contact if or Partner if) how will we manage that?.
