Hi Kim,
kwpsd:
When you upgraded to Jasper Studio 5.6.0, did you also upgrade the Servoy JasperReports Plugin to 5.0.0a2 per the Servoy Forge wiki?
Yes we did.

Although Jasper recommends using the Groovy language for reports, we found that it causes problems with the Plugin. Consider switching your report language to Java for better compatibility with the Plugin. Be warned, things that were permissible in Groovy will generate errors when you switch to Java (ask me how I know this). Sometimes, a report will not run, and no errors are generated. Other times, the error message may be misleading.
Thanks for the tips, we will have a look at that.
