[JBoss jBPM] - Error Saving ProcessInstance using AssignmentHandler

by johnhurtchan

Hi, My code does a token.signal(). Then saves does a successful JbpmContext.save(ProcessInstance). But, when I add a AssignmentHandler for a Task in the Next Node, where I try to set the ActorID, I get a hibernate exception below... object references an unsaved transient instance - save the transient instance before flushing: org.jbpm.graph.exe.Token My code looks like this... public class AssignmentHandler extends BaseHandler implements AssignmentHandler | { | public void assign(Assignable assignable, ExecutionContext executionContext) | { | ContextInstance contextInstance = (ContextInstance)(executionContext.getProcessInstance()).getContextInstance(); | TaskInstance task = executionContext.getTaskInstance(); | task.setActorId(123); | } | } What do I need to do to fix it? I tried to modify that code above to try to save the TaskInstance that I modified the ActorID, but still get the same error... public class AssignmentHandler extends BaseHandler implements AssignmentHandler | { | public void assign(Assignable assignable, ExecutionContext executionContext) | { | ContextInstance contextInstance = (ContextInstance)(executionContext.getProcessInstance()).getContextInstance(); | TaskInstance task = executionContext.getTaskInstance(); | JbpmContext jbpmContext = Config.jbpmConfiguration.createJbpmContext(); | TaskInstance myTask = jbpmContext.getTaskInstanceForUpdate(task.getId()); | myTask.setActorId(user.getName()); | jbpmContext.save(myTask); | jbpmContext.close(); | } | } Help!

if you google that class you will find this: https://springmodules.dev.java.net/docs/reference/0.6/html/jbpm31.html This tells you that the process definition will be deployed every time that you start up your server View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4191373#4191373 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4191373

Wouldn't "drop-create" drop all the tables and therefore I'd never see more than one instance? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4191363#4191363 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4191363

[JBoss jBPM] - How to get a Bpel Process Instance through API?

by dhanushgopinath

Hi, I have deployed a BPEL and I am invoking it through a SOAP UI. I want to get this ProcessInstance through API. I tried using GraphSession.findProcessInstances(procDefId), but it returned an error saying "couldn't load process instances for process definition '1'" I checked the DB and found out that there are no entries in the JBPM_PROCESSINSTANCE table. But there are entries in JBPM_PROCESSDEFINITION table of the process definition deployed. Where are the Bpel Process Instances stored then? And how do I obtain them. Please help. Thanks in Advance Dhanush Gopinath View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4191357#4191357 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4191357

by amybasu

I am trying to configure jbpm 3.1.4 and it says, "The simplest way to configure jBPM is by putting the jbpm.cfg.xml configuration file in the root of the classpath", What does it actually mean by the "root of the classpath". where do i need to place the jbpm.cfg.xml file?? If somebody can help me, that will be great.

Look in your hibernate.cfg.xml file if your hbm2ddl is set to drop-create... this may be the cause View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4191342#4191342 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4191342
