[Alexandru Popescu]

Maybe you can be more specific than a simple stack trace.
The first guess is that the mapping for a relation results in a class cast exception.
Inside the trace there is also something interesting: some packages with 2 points (com.src.prts.action..data.config.datacatalog.EJSCMPDataGroupHomeBean).
