String respond = "SOME_VALUE";
Map result = new HashMap();
result.put("answer", respond);
ContentData contentData = null;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream out;
try {
out = new ObjectOutputStream(bos);
out.writeObject(result);
out.close();
contentData = new ContentData();
contentData.setContent(bos.toByteArray());
contentData.setAccessType(AccessType.Inline);
} catch (IOException ioe) {
ioe.printStackTrace();
}
localTaskService.complete(taskId, userName, contentData);
My process has a sequence of human tasks.
When I ran the code above, the first task executed fine, but the second task gives me:
java.lang.String cannot be cast to org.jbpm.task.utils.MarshalledContentWrapper
Any idea why it suddently doesn't work?
Full stack trace:

Any help is greatly appreciated.

[jBPM] - JBPM - Catch Intermediate Signal fails sometime

| | I have added "Signal Intermediate Event" to a human-task as a boundary-event as I have given in previous question (http://stackoverflow.com/questions/14473411/jbpm-5-human-task-recall).
Sometimes the signal is processed successfully and *sometimes* it is *NOT*. JBPM runtime just updates the process-instance-info and doesn't process the signal.
I am using +StatefulKnowledgeSession.signalEvent()+ , it is just updating the ProcessInstanceInfo at the backend and the event doesn't cancel the current activity in progress
What could be the problem ? Any bug related to this 'Signal Intermediate Event'? .
