title: "The Report is empty" - is bug?
body: <p>I've created report with 3 parameters in iReport and it's running successfully. The report is execute MS SQL stor proc with 3 parameters:</p>
  
  <ol>
  <li>startdate;</li>
  <li>enddate;</li>
  <li>dept_nm (department name);</li>
  </ol>
  
  <p>iReport gives good result. As soon as I exported jrxml file to JasperReports Server 4.1 I have message "The report is empty".</p>
  
  <p>In the Repository under JasperReports Server I've created controls for dates parameters and single list values for dept_nm parameter.</p>
