Should this work with shortcut fields?
I have a query that is grouped on a category name (sc_Status) but I want to sort on sc_StatusCode to override the alphabetic sort of sc_Status, but when I put the following into initialisation it still sorts by the Grouping
var ds = config.dataSource;
ds.serverSorting=false;
ds.sort = {field: "sc_StatusCode", dir: "asc"};
