Custom fork - jbpm 3
Hi I'm trying to make a custom fork. The number of the Transitions is dynamic and different in each process instance. In the process definition I have added one Transition leaving from the fork. A loop in its action handler, creates new tokens for 1-n times and lets the current token to do the n Transition.
public void execute(ExecutionContext executionContext) throws Exception {
String parts = (String)executionContext.getContextInstance().getVariable("txtParticipantList");
String p = (String)executionContext.getContextInstance().getVariable("tmpParticipant");
String[] users = parts.split(",");
if (p == null || p.equals("")){
Transition transition = executionContext.getTransition();
for (int j=0; j<users.length-1; j++) {
String user = users[j];
Token newToken = new Token(executionContext.getToken(), "dist." + j);
//newToken.setTerminationImplicit(true);
executionContext.getJbpmContext().save(newToken);
ExecutionContext newExecutionContext = new ExecutionContext(newToken);
newExecutionContext.setVariable("tmpParticipant", user);
newExecutionContext.setVariable("pCount", Integer.toString(users.length));
executionContext.getTransitionSource().leave(newExecutionContext, transition);
}
executionContext.setVariable("txtParticipant", users[users.length-1]);
executionContext.setVariable("pCount", Integer.toString(users.length));
}
else{
executionContext.getContextInstance().setVariable("txtParticipant", p);
executionContext.setVariable("pCount", Integer.toString(users.length));
}
}
The swimlane for the task after the fork is
<swimlane name="reviewer"> <assignment expression="variable(txtParticipant)"/> </swimlane>
My problem is that the 'txtParticipant' although is set, the delegation doesn't see. It thinks that is null and throws delegation exceptions.
I was based on that:

Any ideas?
