The Conditional Branching example does not work, because both constants fire, and one of them is picked by semi-random as the result. The reason is that the conditional fireing still fires even on an error. A dummy workflow with a string constants "Coordinated from" a beanshell script that does Thread.sleep(5000), shows that coordination works in principle. However, if the beanshell is changed to throw an Exception, the string constant will still be produced.
