Hello everynone. My first post. I think I read every post about the jBpmContext and nothing gave me the solution...

I'm using jBPM 3 with SEAM. I launch an asynchronous event which launches a ProcessInstance.

I am using another asynchronous event to cancel the previously launched ProcessInstance.

@Observer("builderObserver")
    public void startProcessForBuilder(final PackageConfiguration packageConfiguration, final Package pack) {
        try {
            final JbpmConfiguration jbpmConfig = JbpmConfiguration.getInstance();
            final JbpmContext jbpmContext = jbpmConfig.createJbpmContext();
            final GraphSession graphJbpm = jbpmContext.getGraphSession();
            final ProcessDefinition processDef = graphJbpm.findLatestProcessDefinition("builder");

            final ProcessInstance processInstance = processDef.createProcessInstance();
            processInstance.getContextInstance().setVariable("packageConfigurationId", packageConfiguration.getId());

            jbpmContext.save(processInstance);
            pack.setJbpmProcessId(processInstance.getId());
            processInstance.getContextInstance().setVariable("packLauncher", pack);

....


@Observer("cancelBuilderObserver")
    public void cancelProcessForBuilder(final Package pack) {
        try {
            final JbpmConfiguration jbpmConfig = JbpmConfiguration.getInstance();
            final JbpmContext jbpmContext = jbpmConfig.getCurrentJbpmContext();
            final GraphSession graphJbpm = jbpmContext.getGraphSession();
            final ProcessDefinition processDef = graphJbpm.findLatestProcessDefinition("builder");
            final ProcessInstance processInstance = graphJbpm.getProcessInstance(processDef.getId());

...


But when I do jbpmConfig.getCurrentJbpmContext(); the value is null. It is probably due to different transactions.
I just want to be able to end a processInstance using its id.

Could you please help me?

Thanks.
