I've a problem when including in PosDB (point_of_sale.DB) class.

as soon as i call this._super() on e.g. "get_product_by_category" function, the PoS is not starting. When i look in the browser dev-tools is see, that there is an infinite loop in rendering different widgets. 

in 15.0 i've done this super call exactly the same and it is working correctly.

has someone an idea how i should call _super function in v 16.0?

Example:

var PosDB = require("point_of_sale.DB");
PosDB.include({
    get_product_by_category: function(category_id) {
    // this creates an infinite loop on rendering widgets
    var products = this._super.apply(this, arguments);
    return products;
    },
});

Thanks in advance,
