I designed a report that uses a Hibernate Data source. I can see the values in the designer. However, when I was trying to view it in my Seam application, the DataPresentationEngine throws an error. Here is the stack trace:

Can not load the report query: 11. Errors occurred when generating the report document for the report element with ID 11. 
Error.ReportQueryLoadingError2 ( 1 time(s) )
detail : org.eclipse.birt.report.engine.api.EngineException: Can not load the report query: 11. Errors occurred when generating the report document for the report element with ID 11.

This does not happen, if I use "run" or "preview" in the attribute "designType" instead of "frameset". It also does not happen with reports that use an SQL data source. And, yes, I copied the jdbc driver to WEB-INF\platform\plugins\org.eclipse.birt.report.data.oda.jdbc_2.6.2.r262_v20110127\drivers

Reproducible: Always

Steps to Reproduce:
1. Create a report with a hibernate data source
2. Try to show it within a Seam application
