I'm evaluating jbpm 4 (RC1) and it has some nice new features. However I'm missing the exception handling in jpdl like in JPbm 3. I cannot find any tags to define an exception handler in an xml file. Is it currently only available when creating a processdefinition through code (with the builders...) or are you still working on that.
This feature will not (YET!) be available in 4 GA. It will be introduced later. Didn't had a high enough priority...
