isIgnorePagination - Hangs in a Scriptlet report

[raffimd]

Hi,

In a jasperreport, I observed I was using isIgnorePagination is set to true. I have removed that, the report is hanging after the JRDataSource calls (next()) gets complete.

I use Scriptlet in this report to generate the data for the Pie Chart which is printed in the Summary Page.

 

If I add the isIgnorePagination="true", it is working fine. Since I use Virtualizer, I do not want to set the

isIgnorePagination attribute to true.

 

Any clues, why the report is hanging when I set the isIgnorePagination attribute to true?

When I ran the report with debug log level, I found that the JasperReports engine is ending up StackOverFlow condition.

Code:

HashMap and AbstractMap calls goes into infinitive recusrsive loop.

If I remove the subreports in the summary, the report is coming up.

Can't I populate JRDataSource implementation using a scriptlet and use that datasource for the chart subreport in the summary?

My Environment:

Jasper Reports - JavaFlow 1.3.2

JDK 1.6

I included the src of the jasperreports in Eclipse and debugged. Looks like it has some problem printing the subreport in the summary. Don't know whether it was a Java Continuation problem, or Virtualizer problem.

Just before the StackFlow error, I got the following stack

 

Code:

JRVerticalFiller.addPage(boolean) line: 1182	
JRVerticalFiller.fillTitle() line: 285	
JRVerticalFiller.fillReportStart() line: 224

JRFillBand.fill(int) line: 282	
JRVerticalFiller.fillSummarySamePage() line: 888	
JRVerticalFiller.fillSummary() line: 820	

 

After this, in JRVerticalFiller.addPage() - Line 1185, the code is suspending the Continuation Subreport Runner. I could not understand why it is suspending...

After that See the StackOverFlow Error.

 

Does anyone use Javaflow and Virtualizer together and have Subreport in the Summary band?

 

Any help is really appreciated.
