Hi All, I have programmatically defined a workflow and when it executes I get this error. Apparently, within the ExecutionContext, the transitionSource variable is null. How do I assign this variable? Thanks E Caused by: java.lang.NullPointerException at org.jbpm.graph.def.Transition.fireSuperStateLeaveEvents(Transition.java:181) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4143579#...
