Hi guys

I have this error that started to appear when i run my report in Jaspersoft Studio 5.5. I havent changed anything, increment type is set to none. I am stuck as it seems I cant find the problem anywhere.

Error:

Ok. I know this response is very late but I ran into this issue today
I am posting in the hope that this will save someone some time.

When you have a sub report that returns values and you do a calculation eg sum it will generate the following XML.

<returnValue subreportVariable="SubReport_SysVar_SubTotal" toVariable="MainReport_SysVar_Total" calculation="Sum"/>

In the "Subreport Return Values" screen you get a table with 4 columns  the last one is Incrementer Factory Class.

If you have tried to do any calculation or even just looked into the Incrementer Factory Class option in this screen it will add the
incrementerFactoryClass option to the setting.

<returnValue subreportVariable="SubReport_SysVar_SubTotal" toVariable="MainReport_SysVar_Total" calculation="Sum" incrementerFactoryClass=""/>

This will cause you to get the error.

Quick an easy fix is to remove the incrementerFactoryClass="" in the source file and save.

I had the same error and your fix worked for me as well.

[r.vandenheuvel]

you helped me really. Thank you! @JASPER TEAM: why is this bad behaviour/bug still existing? I'm working with the integrated Eclipse iReport plugin.
