compensating methods for long runnig executions

[idyuce]

Hi everybody,
Did anynone implement any compensating method or approach using JBPM while developing applications for long running process blocks or executions? i mean undoing operations executed before any error met while executing process.
if somebody did it, i will appreciate if he/she shares ideas with us.
BTW, i am not asking classical rolling back transactions for two pahse commit cases on short running blocks or executions.

thanks.

See the topic implementing undo in the design forum.

BTW, you live in a wonderful city! Hope I get to see it some day.

We just made "undo" transitions were applicable, because our "undo's" are business-related undo's.
If you need something like a real compensation, you could see if you could get away with an exception handler, which parks the process in a custom node.
