Ebean查询不正确的结果

Question

我正在学习游戏框架，我希望列出一些订单，然后在单击订单后将提供其中的产品详细信息。我有正常工作的订单列表（索引类中的标题模型），但是单击该订单时，它会为每个不正确的订单提供相同的产品详细信息（使用产品模型显示类）。任何建议都将非常感谢

    public Result index(){

            List<Heading> headings = Ebean.find(Heading.class)
                    .where()
                    .eq("CustomerID", "74")
                    .orderBy("DateOrder desc")
                    .setFirstRow(0)
                    .setMaxRows(10)
                    .findList();
            return ok(index.render(headings)) ;
        }


        public Result show(Integer id){
                        List<Product> products = Ebean.find(Product.class)
                        .setFirstRow(0)
                        .setMaxRows(10)
                        .findList();
                return ok(show.render(products)) ;

        }
