Description Philippe Marsteau CLA 2011-11-07 10:34:15 EST 
Build Identifier: Eclipse Build id: 20110916-0149, BIRT Framework 3.7.1.v20110905-BDF9E8OGTzuHfoz-Au7-CWvXDn6N

I can't generate some dataset because of code bug in org.eclipse.birt.data.engine.executor.DataSourceQuery, assuming IOdaDataSetDesign where a IBaseDataSetDesign is returned. Specifically, a org.eclipse.birt.data.engine.impl.JointDataSetAdapter is attempted to be casted to a IOdaDataSetDesign, which fails with the error in the title.

See attached stacktrace for more details.

Line in problem:
resultMetadata = getMetaData( (IOdaDataSetDesign)session.getDataSetCacheManager( ).getCurrentDataSetDesign( ), odaStatement );


Reproducible: Always

I tried to design a report using Joindataset in subquery but cannot reproduce it.
Could you attach sample report can reproduce it?
