invocation of method componentEvent in org.activit.explorer.ui.task.TaskDetailPanel$4 failed

aneeque — Thu, 18 Jul 2013 14:43:05 GMT

HelloI am trying to invoke a WS from my running process. I get the following error when the process reaches the WS stage. I use the Activiti in action example from chapter 11 as a reference but I am stuck on this error now. Can you please suggest a solution.Caused by: java.lang.ArrayIndexOutOfBounds

Can you add the BPMN xml (at least the WS-element) in a code-block? So we can see how your definition looks.

Re: invocation of method componentEvent in org.activit.explorer.ui.task.TaskDetailPanel$4 failed

frederikherema1 — Fri, 19 Jul 2013 09:04:05 GMT

What is the result if you call the web service yourself?

Is it possible to debug the value of "results" in:

 private MessageInstance createResponseMessage(Object[] results, Operation operation) {
    MessageInstance message = null;
    MessageDefinition outMessage = operation.getOutMessage();
    if (outMessage != null) {
      message = outMessage.createInstance();
      message.getStructureInstance().loadFrom(results);
    }
    return message;
  }

Hi again

Yep the problem was with the result variable.

1. I had mistakenly exchanged the sourceRef and targetRef of the dataOutputAssociation.
2. Result was always returning a null charachter (I dont know if this really crashes it, but I changed this as well)

The process works fine now. Thumbs up for the book example and your support. thanks alot!

Best regards
Aneeque
