When the remote call returns an empty array "[]" to the combobox, should the combobox clear existing options or should there be no change?
e.g.
$('#billingYear').combobox('reload', '/controls/ajax.aspx?a=getYears&Customer_Id=' + x + '&Serial=' + y);
This call can return "nothing" as a valid response, e.g. "[]". I would expect the combobox to clear all existing values. Instead it stays unchanged.
