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

Hello

I 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.

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

Hello

Thankyou for your reply. I copy the whole bpmn file below, its just a simple request approval test process.

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) {<br>&nbsp;&nbsp;&nbsp; MessageInstance message = null;<br>&nbsp;&nbsp;&nbsp; MessageDefinition outMessage = operation.getOutMessage();<br>&nbsp;&nbsp;&nbsp; if (outMessage != null) {<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; message = outMessage.createInstance();<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; message.getStructureInstance().loadFrom(results);<br>&nbsp;&nbsp;&nbsp; }<br>&nbsp;&nbsp;&nbsp; return message;<br>&nbsp; }

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

No worries, thanks for sharing the solution!
