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
	at org.eclipse.birt.core.util.IOUtil.writeInt(IOUtil.java:226)
	at org.eclipse.birt.core.util.IOUtil.writeObject(IOUtil.java:674)

	at org.eclipse.birt.report.engine.api.impl.RunAndRenderTask.doRun(RunAndRenderTask.java:180)

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

Is it a known issue with BIRT 3.7.1 or Am I doing something wrong? I'm attaching my test case below(A rptdesign file and a xml data file).

Please help me to solve this issue.

Thank you.

This does appear to be a bug for the runningcount aggregate. Can you
log a bugzilla request for this? To work around it can you add the
aggregate to the dataset as a computed column. See attached example.
