Hi,

I'm trying to create a report with a RunningCount aggregation. The report is working fine when generated with the WebViewer within the report designer. But when the report is exported as a PDF from the designer it throws an NullPointerException as given below.

Caused by: java.lang.NullPointerException

All other report forms like excel, word etc also is throwing the NullPointerException.
