Hi All,
I have created new BIRT report. When I run it (no matter if in report designer or in RTC), I am getting the error below. What is the work around I can use?

It happens when I select many values from multiselect param in the report. I am using RTC 4.0.4.

Here is error message

org.eclipse.birt.report.service.api.ReportServiceException: Error happened while running the report.

Fixed. For unknown reason one of report sections has not been deleted from xml source. Removing this section manually fixed the issue.

Here is reference eclipse bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=423150
