Is there a way to see how many lines of detail a report has? We would like to do something like this or expose a method like this. Thanks, Tom Code:final JasperPrint jasperPrint = JasperFillManager.fillReport(reportDesign,map,dataSource);if(jasperPrint.hasDetail) { reportList.add(jasperPrint);}

We have a text field on a Subreport with 173 carriage returns causing a crash(user supplied data). If we remove this data it works fine. We have Stretch Type for this text field No Stretch, the Print When Detail Overflows is false and the Stretch with Overflow. Now we plan on changing the interface as well, but is it possible to make this work with JasperReport? Thanks, Tom

We have a web application deployed to Websphere 6.1.0.19 on Windows. We occasionally see this ConcurrentModificationException on a few of our reports. We are using JasperReports 2.0.5 in production.
