[jboss-user] [JBoss jBPM] - Super State

[petia]

Hi,

I am trying to use the Super State construct in jBPM 3.1.4 and I have problems with it. As I am not able to define the components of a super state in the graphical editor (which only provides support for defining activities for a super state), I am directly editing in the xml definition of the process. I have the following process.


  | <?xml version="1.0" encoding="UTF-8"?>
  | 
  | <process-definition
  |   xmlns="urn:jbpm.org:jpdl-3.1"  name="SuperState">
  |    <swimlane name="ernie">
  |       <assignment expression="user(ernie)"></assignment>
  |    </swimlane>
  |    <start-state name="start">
  |       <task name="start-task">
  |       	<assignment expression="user(ernie)"></assignment>
  |       </task>
  |       <transition name="to phase 1" to="phase1/task1"></transition>
  |    </start-state>
  |    <super-state name="phase1">
  |       <task-node name="start-phase1">
  |       	<task name="task11"> 
  |       		<assignment expression="user(ernie)"></assignment>
  |       	</task>
  |       	<transition name="a" to="task2"></transition>
  |       </task-node>
  |       <task-node name="end-phase1">
  |       	<task name="task12" swimlane="ernie" > </task>
  |       	<transition name="t" to="../task3"></transition>
  |       </task-node>     
  |    </super-state>
  |    <task-node name="phase2">
  |       <task name="task2"> 
  |       	<assignment expression="user(ernie)"></assignment>
  |       </task>
  |       <transition name="to end" to="end"></transition>
  |    </task-node>
  |    <end-state name="end"></end-state>
  | </process-definition>
  | 

I successfully deploy the process and I am able to run it until task11. It gets allocated to the defined user, but when selected for execution the following error message is displayed.

Are Super States supported in jBPM 3.1.4? If yes can you see what is wrong with my process definition?

Kind regards, Petia
