Yep - definitely a bug. I've checked out the code now to confirm it. The code
is casting to GenericElement via the SemanticElement interface, but our friend
ProcessDefinition can't be cast that way as it doesn't extend GenericElement.
I've updated Play to show how it's blowing up. (This reflects the code pattern
used in GenericElementXmlAdapter).
import org.jbpm.gd.common.model.GenericElement;
| import org.jbpm.gd.common.model.SemanticElement;
| import org.jbpm.gd.jpdl.model.ProcessDefinition;
|
|
| public class Play {
|
| public static void main(String[] args) {
|
| ProcessDefinition pd = new ProcessDefinition();
| //GenericElement ge = (GenericElement)pd;
|
|
| SemanticElement se = (SemanticElement)pd;
| GenericElement ge = (GenericElement)se;
| }
| }
|
This compiles happily and gives a runtime error...

Case proved I think! Now, how do I raise a bug report?!
(I'm still not clear how some of you guys did get it working. Maybe you're
using a different version of the designer plugin in eclipse, or maybe this has
only sneaked into the windows version somehow)?
Cheers,
Ian.
