title: JasperServer - null values for input controls
body: <p>Recently I got some help with grouping when a user enters a null value into an input control (<a href="https://stackoverflow.com/questions/10897962/rolling-up-groups-in-jaspersoft-ireport">&quot;Rolling up&quot; groups in Jaspersoft iReport</a>). I am using iReport/JasperServer Professional 4.5.1. My three levels of grouping are pharmacy, facility, and packaging type.</p>
  
  <p>After deploying the report to <code>JasperServer</code>, I am having some trouble with nulls. I unchecked "always prompt" for my input controls, and when the report opens the first time it acts as though it has received null values for all input controls and groups appropriately (which is what I want). The display mode for my input controls is "in page", so they're displaying on the left-hand side of the screen. When I then try to select one pharmacy and re-run the report (expecting aggregate values for facilities and packaging types, since I didn't select anything for those controls), the report performs like the aggregate code doesn't exist, and lists all facilities and all packaging types.</p>
  
  <p>However - if I save that one selected pharmacy as a saved input control, then go back out to the repository and run the report using the saved input control, it works fine, and aggregates all facility and packaging type data.</p>
  
  <p>Any thoughts?</p>
  
  <p>Thanks,<br>
