null result from getFormattedTotalIncTax()

[BoJo]

I am getting a null result when calling AdminOrder.getFormattedTotalIncTax() using the JasperReports scriptlet below. I can see proper values in the orders_totals table.

The parameter and field values have been verified. For example, I passed an incorrect sessionId at one point and received a stack trace (as expected).

Any help is appreciated,

Bob

---------------------- JasperReports scriptlet method ----------------------------
    public String getFormattedTotals() throws JRScriptletException {
        String formattedTotals = null;
       
        KKAdminIf kkEngine = (KKAdminIf)this.getParameterValue("kkAdminEng.class");
        String sessionId = (String) this.getParameterValue("sessionId");
        Integer orderId = (Integer)this.getFieldValue("orders_orders_id");
        AdminOrder adminOrder;
        try {
            adminOrder = kkEngine.getOrderForOrderId(sessionId, orderId.intValue());
        } catch (KKAdminException e) {
            throw new RuntimeException(e);
        }
        formattedTotals = adminOrder.getFormattedTotalIncTax();
   
        return formattedTotals;
    }

Looks like getFormattedTotalIncTax() is deprecated.
