I have the following process definition:
| <process-definition>
| <start-state>
| <transition to='CreateWOHandler'/>
| </start-state>
| <node name='CreateWOHandler'>
| <action class='DTVProcess.CreateWOHandler' />
|
| <transition to='XPort'/>
| </node>
| <node name='XPort'>
| <action class='XPortHandler' />
| <transition to='VTPS'/>
| </node>
| <node name='VTPS'>
| <action class='VTPSHandler' />
| <transition to='BFRename'/>
| </node>
| <node name='BFRename'>
| <action class='BFRenameHandler' />
| <transition to='end'/>
| </node>
| <end-state name='end' />
| </process-definition>
|
|
I save this provess defintion and then run an insatnce of it:
|
| processDefinition2.setName("CustomNodeTest");
| JbpmConfiguration config = JbpmConfiguration.getInstance();
| JbpmContext context = config.createJbpmContext();
|
context.getGraphSession().saveProcessDefinition(processDefinition2);
|
| ProcessInstance loadedProcessInstance = new
ProcessInstance(processDefinition2);
| context.save(loadedProcessInstance);
| loadedProcessInstance.signal();
|
|
No I am susoending the process in one of the Action handlers ('XPortHandler'),
as soon as I do this I get an exception thrown from the
MessagingSession.SuspendMessages(Token token)

If I dont save the process definition at the begining, it goes through fine.
Please let me know if you see a problem.
