Hello everybody,

I want to modify the method which display the product's price in list price. To do that i followed the answer posted in another question (not enough karma to post link sorry) but it's not work with my code:

openerp.openerp_pos_models_ttc = function(instance) {
    instance.openerp_pos_models_ttc = {};
    var module = instance.point_of_sale;
    var _super_ = module.Orderline.prototype.get_display_price;
    module.Orderline.prototype.get_display_price = function(){
        console.log('display price');
        _super_.call(this);
        return 1000;
    };

};

What am i doing wrong?

There is my __openerp__.py :

{
'name': 'pos_ttc',
    'version': '1.0',
    'category': 'Sales Management',
    'description': """
        """,
    'depends': ['point_of_sale'],
    'data': [
    ],
    'demo':
        [
    ],
    'test':
        [
    ],
    'js': [
    'static/src/js/models_ttc.js',
    #'static/src/js/main.js',
    ],
    'installable':
        True,
    'auto_install':
        False,
}

I work on OpenERP 7.

Thanks.
