Subject Revisiting the step mechanism in DebuggerSupport class
Date Mon, 10 Aug 2009 09:24:14 GMT
Hi all,
When the step operation is invoked in DebuggerSupport class, via the
BpelManagementFacadeImpl, it gives the following error. Can anybody
give me a hint on why this kind of a exception would occur?

Best Regards,
Denis Weerasiri.
