Hi all There is a bug on V6.1 regarding .csv files. On update time, they are treated as noupdate=False, despite the documentation says they should be treated as noupdate=True The attached patch correct the issue. It was already reported on bug #980369, but for a reason I don't known, never answered or treated This bug can cause big difficulties, because .csv are used in two critical cases: initialization of the security records and initial customer data load. In the first case (security descriptors), when you update the module, ALL CHANGES introduced to fine tune the security of the database are lost. That could be something easy to see (i.e. no access) or it could generate a major security breach for customer data, that could be eventually recognized when a (good) user reports problems, and thus the (bad) users will get granted access to restricted data for a while! In the second case, initial customer data will be most probably updated by the customer on its daily operation. All changes will be LOST on an update of the initial modules (something common if you are on the initial phases of a project). Again, a critical case for many installation I strongly believe this is a major problem. I hope you get some attention from OpenERP 2012/7/12 Don Kirkby
