Q:

Kendo DataSource $expand on multiple fields

I'm trying to get the $expand directive to work as below.
This works fine if I expand on on a single entity, but fails for both when expanding on more than one. (i.e. $expand: "Product", works works fine)
Anyone succeeded with this?
  dataSource: {
                type: "odata",
                transport: {
                    read: {
                        url: "odata/OrderDetail",
                        dataType: "json",
                        contentType: "application/json",
                        data: {
                            $expand: ["Product", "Category"]
                        }
                    }

A:

$expand: "Product,Category"
I assumed that "$expand" was built into KUI datasource.  But the  data:{ } param. allows arbitrary specification (which it injects into the request).
So, one can use $mickeymouse, and long as your odata controller handles it
