Hello Rifakat. In my opinion when a function field with many2one have the option store=True, the orm should read the id from the database and after link it to the object related. And if the option store=False is set it should always read it from the function. Moreover In my case I also use the inv_fnc to set the value. Indeed depending of the context my field is in readonly or not, and so the user can filled the field manually so I have to read it from the database because I can not compute it as it was set manually.
You can check the code where I used it http://bazaar.launchpad.net/~akretion-team/openobject-addons/base_external_ref_error_managment/revision/5485 in the file sale Extract of the code : def _get_referential_id(self, cr, uid, ids, name, args, context=None): res = {} for shop in self.browse(cr, uid, ids, context=context): if shop.shop_group_id: res[shop.id] = shop.shop_group_id.referential_id.id else: #path to fix orm bug indeed even if function field are store, the value is never read for many2one fields cr.execute('select referential_id from sale_shop where id=%s', (shop.id,)) result = cr.fetchone() res[shop.id] = result[0] return res def _set_referential_id(self, cr, uid, id, name, value, arg, context=None): shop = self.browse(cr, uid, id, context=context) if shop.shop_group_id: raise osv.except_osv(_("User Error"), _("You can not change the referential of this shop, please change the referential of the shop group!")) else: if value == False: cr.execute('update sale_shop set referential_id = NULL where id=%s', (id,)) else: cr.execute('update sale_shop set referential_id = %s where id=%s', (value, id)) return True def _get_shop_id(self, cr, uid, ids, context=None): shop_ids=[] for group in self.pool.get('external.shop.group').browse(cr, uid, ids, context=context): shop_ids.append([shop.id for shop in group.shop_ids]) return shop_ids 'referential_id': fields.function(_get_referential_id, fnct_inv = _set_referential_id, type='many2one', relation='external.referential', string='External Referential', method=True, store={ 'external.shop.group': (_get_shop_id, ['referential_id'], 10), }), As you can see I had an ugly patch to force to read into the database the value of the id when the function is call. In the case that fnct_inv is used with store=True, we don't have the choice the orm have to read it the value from the database because the value can not be computed. Hope my explication can help you.

The problem is that the field is still read from the function and never from the database. It look like the option store=True is never use in reading. exemple add this field to sale_shop def _get_test_id(self, cr, uid, ids, name, args, context=None): print 'get test' res={} for id in ids: res[id] = 1 return res 'test': fields.function(_get_test_id, type='many2one', relation='product.product', string='Product', method=True, store=True), And open the sale shop. You will see that each time the sale_shop is open the field test is read from the function "_get_test_id" and not directly from the database. I have this bug with the last version of openerp 6.0 I also send a mail to the support team.
