I have recently started to try on the new Odoo 8.0 (demo) on my Ubuntu 12.04 LTS server (32bits).   Everything are working fine until I started to add the customized fields on "res.partner.form" view.    The system still worked well after I successfully added two new fields (x_PartnerTaxID, x_OfficeType) on this view.    However, the system went wrong after the third field (x_BranchID), added on this view.   This error was repeatable and it seems to be a kind of BUG in this new version. (I tried exactly the same thing on V7.0 without any problem).     Is there anybody know how to get his fixed?    Please kindly help.     

Here there are, the error message pop up on screen once the third customized field was added and I clicked on the menu "Purchase" --> "Suppliers"
