Hi,
at some point in my application I reload my session:
JPAKnowledgeService.loadStatefulKnowledgeSession(sessionId, kbase, config, env);
then my process instance:
WorkflowProcessInstance processInstance = (WorkflowProcessInstance) ksession.getProcessInstance(processInstanceId);
and then try to set a process variable:
processInstance.setVariable(name, value)
which fails :
java.lang.NullPointerException
at org.jbpm.process.instance.impl.ProcessInstanceImpl.getProcess(ProcessInstanceImpl.java:68)
at org.jbpm.process.instance.impl.ProcessInstanceImpl.getContextInstance(ProcessInstanceImpl.java:133)
at org.jbpm.workflow.instance.impl.WorkflowProcessInstanceImpl.setVariable(WorkflowProcessInstanceImpl.java:238)
...
The reason is: the variable InternalKnowledgeRuntime kruntime in ProcessInstanceImpl is null.
Is it a bug or is there another way to load the process instance?
Regards,
Oleg

Hello there,
I have a problem with mapping the Human Task output to process variables. My code is inspired by the https://community.jboss.org/people/bpmn2user/blog/2011/09/21/jbpm5-web-ex... https://community.jboss.org/people/bpmn2user/blog/2011/09/21/jbpm5-web-ex... blog post.
I run it in Tomcat 6, using the Mina HT service.

This is how I start the process:
public RunningProcess launch(Workflow workflow, Map<String, Object> parameters) throws WorkflowException {
Map<String,Object> processParams = new HashMap<String,Object>();
processParams.put(RunningProcess.DATA, parameters);
try {
// start user transaction
UserTransaction ut = (UserTransaction) new InitialContext().lookup("java:comp/UserTransaction");
ut.begin();
// start process
ProcessInstance pi = this.ksession.startProcess(workflow.getId(), processParams);
this.ksession.fireAllRules();
// commit
ut.commit();
return new ProcessImpl(pi);
} catch (Exception e) {
log.debug("Error starting workflow [" + workflow.getId() + "].", e);
throw new WorkflowException("Error starting workflow.", e);
}
}
RunningProcess.DATA containg the "mgnlData" string, Workflow is my bean holding the process definition data, RunningProcess / ProcessImpl are my wrappers for the ProcessInstace. Then I call this method from:
Map<String, Object> data = new HashMap<String, Object>();
data.put("string", "string value");
data.put("int", 42);
process = manager.launch("test", data);
And how I handle the Human Task:
// prepare data
Map<String, Object> data = new HashMap<String, Object>();
Map<String, Object> mgnlData = new HashMap<String, Object>();
mgnlData.put("int", 1111);
mgnlData.put("string", "new value");
data.put(RunningProcess.DATA, mgnlData);
// start user transaction
UserTransaction ut = (UserTransaction) new InitialContext().lookup("java:comp/UserTransaction");
ut.begin();
// start processing the task
BlockingTaskOperationResponseHandler responseHandler = new BlockingTaskOperationResponseHandler();
this.taskClient.start(summary.getId(), user, responseHandler);
responseHandler.waitTillDone(1000);
// and complete the task
responseHandler = new BlockingTaskOperationResponseHandler();
this.taskClient.complete(summary.getId(), user, map2contentData(data), responseHandler);
responseHandler.waitTillDone(2000);
// commit transaction
ut.commit();
The map2contentData method is based on the code from jBPM5 web example blog post:
protected ContentData map2contentData(Map data) {
ContentData contentData = null;
if (data != null) {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream out;
try {
out = new ObjectOutputStream(bos);
out.writeObject(data);
out.close();
contentData = new ContentData();
contentData.setContent(bos.toByteArray());
contentData.setAccessType(AccessType.Inline);
} catch (IOException e) {
log.error("Problem saving output data.", e);
}
}
return contentData;
}
But it results in the empty process variable in the end (console output):
ENTRY SCRIPT: 425984
DATA: {int=42, string=string value}
Human Task - Entry action
...
Human Task - Exit action
EXIT SCRIPT: 425984
Empty DATA
I expect sort-of PEBKAC error, but I couldn't find what did I forget...

Hi,
I'm using hibernate version 3.5.5 GA and we are using Jboss Tree Cache as Hibernate second level Caching using hibernate-jbosscache-3.3.0.GA, hibernate-jbc-cacheprovider-1.0.2.GA and jboss-cache-jdk50 (treecache). We are experiencing problem for those mapping which uses c*ache-usage="transactional"* along with *timestamp* tag when we try to create a Entity then modify the same entity it throws the below exception.

{code}
Please lead us what causing this issue. Is it Hibernate 2nd level caching is not working as expected or Jboss Tree cache ?
The same operation is working with no issues without *timestamp* to the entity mapping.

[jBPM] - Prevent duplication in XOR gateway

"Prevent duplication in XOR gateway"

--------------------------------------------------------------
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
