<p>Hi!</p>
<p>I want to show report parameters joined with ','( which user choosen) in header of report.</p>
<p>I'm using this expression</p>
<p>if (reportContext.getParameterDisplayText("NewParameter"))</p>
<div>{</div>
<div>var par = reportContext.getParameterDisplayText("NewParameter");</div>
<div>var listOfParams = ""</div>
<div>for (var keys = 0; keys < par.length; keys++)</div>
<div>{</div>
<div>listOfParams+= par[keys] </div>
<div> </div>
<div>But nothing showed in header. </div>
<div>Could someone explain how reportContext.getParameterDisplayText("NewParameter") works?</div>
