16:37:10,491 ERROR [SynchronousDispatcher] failed to execute
*=== Problem description =========================*
When invoking any process from the jBPM console, if the process itself throws an exception
at runtime (Debug logs), the console displays a window with the *Stacktrace* showed above
(printscreen attached). This occurs regardless of the error that occurred within the
process and the process being invoked.
NB: The problem I'm trying to report is *NOT* the exception described in the Debug
log, it's the exception thrown in the console due to the error in the process.
I have been through the jBPM wiki, user forums, etc. but nothing addresses this issue
concretely. What is the cause of this exception and how do I fix it?
Kind Regards,
Adel Haider
