Data contract object not initialized

Hi,

I have written a SysOperationServiceController class and getting the following error whenever i run it.

HU_DataContract object not initialized.

Stack trace

(C)\Classes\HU_CustTesterServiceController\newFromArgs - line 25
(C)\Classes\HU_CustTesterServiceController\main - line 6

I am not sure what is missing, following is the code for the class

class HU_CustTesterServiceController extends SysOperationServiceController
{
}

public static void main(Args _args)
{
   HU_CustTesterServiceController hu_CustTesterServiceController;
    ;

   hu_CustTesterServiceController  = HU_CustTesterServiceController::newFromArgs(_args);
   hu_CustTesterServiceController.startOperation();

}

public static HU_CustTesterServiceController newFromArgs(Args _args)
{
    HU_CustTesterServiceController    HU_CustTesterServiceController;
    HU_DataContract _HU_DataContract;
    CustTable   custTable;
    Query       query;
    IdentifierName className, methodName;
    SysOperationExecutionMode executionMode;


    [className, methodName, executionMode] = SysOperationServiceController::parseServiceInfo(_args );

    // create a new instance of the controller

   HU_CustTesterServiceController = new HU_CustTesterServiceController( className, methodName, executionMode);
    // initialize from args
    // one of the things this will do is read the "parameters" property from the menu item
    HU_CustTesterServiceController.initializeFromArgs(_args);

    // get datacontract
    // the string should be the same as the parameter name!

   _HU_DataContract =  HU_CustTesterServiceController.getDataContractObject('_HU_DataContract');
    // default current date
 _HU_DataContract.parmDate(systemDateGet());


    // check if the record is of type CustTable
    if(_args && _args.dataset() == tableNum(CustTable))
    {
        // cast record
        custTable = _args.record();

        // create new query
        query = new query(queryStr(HU_ForCustomers));
        // add range
        query.dataSourceTable(tableNum(CustTable)).addRange(fieldNum(CustTable, AccountNum)).value(queryValue(custTable.AccountNum));

        // set query on datacontract
    _HU_DataContract.setQuery(query);

    }


    // return a new instance of this controller
    return HU_CustTesterServiceController;
}

Many thanks,
