最新代码table绑定dataType不加载子属性数据

[zhoushijin]

model.dataType({
            name: "SubProduct",
            properties: {
                id: {
                    dataType: "number"
                },
                parentId: {
                    dataType: "number"
                },
                name:{
                }

            }
        });
        model.dataType({
            name: "Product",
            properties: {
                productName: {
                },
                id: {
                    dataType: "number"
                },
                categoryId: {
                    dataType: "number"
                },
                quantityPerUnit: {
                    dataType: "number"
                },
                unitPrice: {
                    dataType: "number"
                },
                unitsInStock: {
                    dataType: "number"
                },
                unitsOnOrder: {
                    dataType: "number"
                },
                subProduct:{
                    dataType: "SubProduct",
                    provider:{
						url:"./service/product/subproduct/{{@id}}",
						method:"POST"
					}
                }
            }
        });
        model.describe("products",{
            dataType:"Product",
            provider:{
				url:"./service/product/product/",
				method:"POST"
			}
        })

最新的代码中，table绑定datatype是不能加载子属性，如代码中加载不到products.subProduct的数据
