I really am at my wit's end here. I have two modules (purchase_control_supplier and search_product_supplier_code) that I want to have running at the same time, and they appear to be incompatible. If I have search_product_supplier_code installed, purchase_control_supplier stops working without fail. I think that it may have something to do with the fact that purchase_control_supplier modifies the search() function, which is called in the name_search() function that search_product_supplier_code uses. Any idea how to fix this? Nothing stands out to me immediately as being wrong. Including the code below

search_product_supplier_code/product.py:

from osv import osv, fields
class product_product(osv.osv):
        _name = 'product.product'
        _inherit = 'product.product'
        def name_search(self, cr, user, name, args=None, operator='ilike', context=None, limit=100):
                if name:
                        if args:
                                args = ['|', ('suppliers_code', operator, '%' + name + '%')] + args
                        else:
                                args = ['|', ('suppliers_code', operator, '%' + name + '%')]
                res = super(product_product,self).name_search(cr, user, name, args, operator='ilike', context=None, limit=100)
                return res
        def _suppliers_code(self, cr, uid, ids, name, arg, context=None):
                res = {}
                prds = self.browse(cr, uid, ids)
                for prd in prds:
                        code = ''
                        for line in prd.seller_ids:
                                code = '%s %s' % (code, line.product_code)
                        res[prd.id] = code
                return res
        _columns = {
                'suppliers_code': fields.function(_suppliers_code, type='char', size=256, string='Supplier Code', store=True),
                }
product_product()

from osv import osv, fields
class product_product(osv.osv):
    _name = "product.product"
    _inherit = "product.product"
    def search(self, cr, uid, args, offset=0, limit=None, order=None, context=None, count=False):
        if context and context.get('supplier_id', False):
            product_limit = self.pool.get('res.partner').read(cr,uid,context['supplier_id'],['supplier_product_limit'])['supplier_product_limit']
            if product_limit:
                #    ids = []
                cr.execute("SELECT distinct(product_id) FROM product_supplierinfo where name = %s" % (context.get('supplier_id')))
                ids = [x[0] for x in cr.fetchall()]
                args.append(('id', 'in', ids))
                order = 'default_code'
        return super(product_product, self).search(cr, uid, args, offset=offset, limit=limit, order=order, context=context, count=count)
product_product()
class res_partner(osv.osv):
    _name = 'res.partner'
    _inherit = 'res.partner'
    _columns = {
        'supplier_product_limit':fields.boolean("Control Supplier Search", help="""If checked, allows you to search only the product in this supplier )"""),
    }
    _defaults = {
        'supplier_product_limit': True,
    }

Any help would be greatly appreciated!
