Problem with XOR gateway

activiti-admin — Sat, 12 Jun 2010 13:55:32 GMT

There is a process model of the shape startEvent - userTask - exclusiveGateway - 3 userTasks - endEventThe problem is, when the first userTask has been completed, the process does not have active tasks.(In contrast, the process works as expected when the first userTask is removed.)XorTest.testXor

It looks like there is no sequence flow going from your first task to the exclusive gateway.
In that case, the process execution will be ended, since that is the required semantics according to the BPMN 2.0 spec (ie an 'invisible' end event following the task)


 if (LOG.isLoggable(Level.FINE)) {
        LOG.fine("No outgoing sequence flow found for " + execution.getActivity().getId() + ". Ending execution.");
      }
      execution.end();
