Hi, I use OE version 7.0 and I have a case like this.

In stock move, on module stock, we have write method defined

def write(self, cr, uid, ids, vals, context=None):
            if isinstance(ids, (int, long)):
                    ids = [ids]
            if uid != 1:
                    frozen_fields = set(['product_qty', 'product_uom', 'product_uos_qty', 'product_uos', 'location_id', 'location_dest_id', 'product_id'])
                    for move in self.browse(cr, uid, ids, context=context):
                            if move.state == 'done':
                                    if frozen_fields.intersection(vals):
                                            raise osv.except_osv(_('Operation Forbidden!'),
                                             _('Quantities, Units of Measure, Products and Locations cannot be modified on stock moves that have already been processed (except by the Administrator).'))
            return  super(stock_move, self).write(cr, uid, ids, vals, context=context)

I want to override it in my custom module become like this one:

def write(self, cr, uid, ids, vals, context=None):
		    if isinstance(ids, (int, long)):
         ids = [ids]
    access = self.pool.get('ir.model.access').check(cr, uid, 'stock.move', 'write', context)
		    if uid != 1 and not access:
			        frozen_fields = set(['product_qty', 'product_uom', 'product_uos_qty', 'product_uos', 'location_id', 'location_dest_id', 'product_id'])
			        for move in self.browse(cr, uid, ids, context=context):
				            if move.state == 'done':
					                if frozen_fields.intersection(vals):
						                    raise osv.except_osv(_('Operation Forbidden!'),
											 _('Quantities, Units of Measure, Products and Locations cannot be modified on stock moves that have already been processed (except by the Administrator).')) 
 return super(stock_move, self).write(cr, uid, ids, vals, context=context)

If I use that method in my custom module, my method will be called but it keep raising exception from the first method too.

I need suggestions how to do it properly in OpenERP/ODOO
