WEBI 4.1 SP3 disable No Data To Retrieve message from coding

When we were in BO 3.1 we were able to disable 'No Data to retrieve in + query' message by commenting out a line in viewer.js file from

directory: AnalyticalReporting.ear\AnalyticalReporting.war\viewers\cdz_adv\language\en\scripts

function displayNoDataToFetch(s,cb)

{

//showAlertDialog("No data to retrieve in "+s,"Retrieving Data",0,cb);

}

How can this can be achieved in WEBI 4.1 ?

thanks,
