Hello All,
I have a action handler that does the following:
| JbpmSessionFactory factory = JbpmSessionFactory.getInstance();
| JbpmSession jbpmSession = factory.openJbpmSession();
| jbpmSession.beginTransaction();
| try
| {
| ProcessInstance pi=executionContext.getProcessInstance();
| jbpmSession.getGraphSession().saveProcessInstance(pi);
| jbpmSession.commitTransaction();
| }
| catch (Exception e)
| {
| e.printStackTrace();
| jbpmSession.rollbackTransaction();
| }
| finally
| {
| jbpmSession.close();
| }
|
This action handler is associated with each transition programmatically, i.e.,
it is not part of the original process definition. The action handler gets
executed when a transition is taken and I see an entry in the process instance
table in db however when I kill the process instance (ctrl-c) and try to rerun
(processinstance.signal()) it by obtaining it from database using the instance
id. However, I am getting the following exception:
java.lang.IllegalStateException: couldn't signal token 'Token(/)' : couldn't
leave node 'null' over its default transition
| at org.jbpm.graph.exe.Token.signal(Token.java:90)
| at
org.jbpm.graph.exe.ProcessInstance.signal(ProcessInstance.java:201)
| at jpl.mipl.pgs.jbpm.JBPMExeEngine.execute(JBPMExeEngine.java:469)
| at jpl.mipl.pgs.jbpm.JBPMExeEngine.main(JBPMExeEngine.java:529)
|
What am I doing wrong? PLEASE HELP.
Sincerely,
Raj
