This was a really good question Andrea, thanks for asking it. I have had the same question. I'm not sure I understand Chris' answer though.
I would like to know how to abort execution of the entire workflow if any of the tasks within the workflow exit with a failure status. Is there such a thing as a "task precondition"? I figured out how to create a workflow precondition (because I don't want my workflow to be triggered to start if there is already one in progress), but, I can't tell if there is a way to set a precondition on a specific task in a workflow.
