Hi Ed, Below is the example which works nicely for me. Note that, the fork and join have the default setting async="false". The transitions "to B1" and "to B2" going out from the Fork node, do not have any conditions specified. The only difference of this example, from a non-working example is that both transitions going out from the Fork node have names, i.e. "to B1" and "to B2" below. I hope this helps, Petia <?xml version="1.0" encoding="UTF-8"?> | | <process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="Fork"> | <swimlane name="Initiator"> | <assignment actor-id="admin"></assignment> | </swimlane> | | <start-state name="start-state1"> | <task name="start-task" swimlane="Initiator"></task> | <transition to="taskA"></transition> | </start-state> | | <task-node name="taskA"> | <task name="taskA" swimlane="Initiator"></task> | <transition to="fork1"></transition> | </task-node> | | <fork name="fork1"> | <transition to="taskB1" name="to B1"></transition> | <transition to="taskB2" name="to B2"></transition> | </fork> | | <task-node name="taskB1"> | <task name="taskB" swimlane="Initiator"></task> | <transition to="join1"></transition> | </task-node> | | <task-node name="taskB2"> | <task swimlane="Initiator" name="taskB2"></task> | <transition to="join1"></transition> | </task-node> | | <join name="join1"> | <transition to="end-state1"></transition> | </join> | | <end-state name="end-state1"></end-state> | </process-definition> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4171118#...
