Auto populate child table in purchase receipt

[lasalesi]

Just a thought, nice code snippet, but is a server-side code required? What if this API call was used:

frappe.call({
    method:"frappe.client.get_list",
    args:{
        doctype:"Item Attribute Value",
        filters: [
            ["supplier","=", frm.doc.supplier]
        ],
        fields: ["parent"],
        parent: "Supplier"
    },
    callback: function (response) {
        /* see above */
    }
});
