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:

I need to get the tasks by status and then start them.
But at some times while retrieveing the tasks im getting the started process id as well and thats in where im getting this exception.
org.jbpm.task.service.PermissionDeniedException: Server-side Exception: User '[User:'admin']' was unable to execution operation 'Start' on task id 287271 due to a no 'current status' match

My mina task handler is running in jboss and the application uses its client to the task operations.
Retrieveing tasks by status:
BlockingTaskSummaryResponseHandler resHandler = new BlockingTaskSummaryResponseHandler();
List<Status>statusls=new ArrayList<Status>();
statusls.add(Status.Reserved);
client.getTasksAssignedAsPotentialOwnerByStatus("admin",statusls, "en-UK", resHandler);
Starting the task:
BlockingTaskOperationResponseHandler responseHandler = new BlockingTaskOperationResponseHandler();
client.start(taskId, userId, responseHandler);
*Is there any thing to do with hibernate or what should i take care to eliminate this replication.?*

[jBPM] - Prevent duplication in XOR gateway
by Erik Pragt

"Prevent duplication in XOR gateway"
To view the discussion, visit: https://community.jboss.org/message/751003#751003
--------------------------------------------------------------
Hi all,
I'm just getting started with jBPM, and I have a small question about XOR gateways. At the moment, our nodes have two endpoints, and the code for one endpoint looks like this:
switch(result) {
case OK:
return true;
default:
return false;
}
While for the other endpoint (pointing to an 'end event'), it looks like this:
switch(result) {
case OK:
return false;
default:
return true;
}
So in the other constraint it's the other way around. To me, this looks like a bit of duplication, and in this example it's not too bad, but in more complex examples, it's trickier. So I was wondering, isn't there a better way to do this? Isn't it possible to create one piece of code, and let true go to one sequence flow, and false to the other, without having the need to duplicate the code? Is something like this possible??
Thanks for the help,
Kind regards,
Erik
