Recursive subreport

Hi all,

I have problem with running recursively subreport in JI.
I have main report which contains subreport and this has as subreport itself. In iReport it works without problem but when i deployed it in JI, after running the report, there is exception:

org.springframework.webflow.ActionExecutionException: Exception thrown executing [AnnotatedAction@1da6868 targetAction = com.jaspersoft.jasperserver.war.action.ViewReportAction@1fcadd3, attributes = map[[empty]]] in state 'verifyData' of flow 'viewReportFlow'; nested exception is java.lang.NullPointerException: null
