Hello Everyone,
I have requirement where i need to show tracking of an workflow. However history for task, Activity, Process intances are saved into corresponding history tables.
But while browsing through JBPM4_HIST_VAR table , i am unable to get ani information about process variables.
please see the following code.
 
  
ProcessInstance pInstance = 

executionService




Map<String, Object> params = new HashMap<String, Object>();
params.put("SubmittalCoordinator", "HO-DWG");
params.put("CivilDepartment", "HO-CIVIL");
params.put("MechanicalDepartment", "HO-MECH");
ProcessInstance pInstance = executionService.startProcessInstanceByKey("workflowStatus", params);
executionService.setVariable(pInstance.getId(), "ProcessInstanceId", "workflowStatus");


repositoryService.createDeployment().addResourceFromClasspath("insight/abg/jbpm/workflowStatus.jpdl.xml").setName("workflowStatus").deploy();
    ProcessInstance pInstance = executionService
      .startProcessInstanceByKey(instanceKey, params);
    executionService.setVariable(pInstance.getId(), "ProcessInstanceId", pInstance);
    ((ExecutionImpl)pInstance).createVariable("someString", "SomeString","string",true);
    Variable variable =  ((ExecutionImpl)pInstance).getVariableObject( "SomeString");                     
    HistoryEvent.fire(new VariableCreate(variable));

//    EnvironmentImpl environment = ((EnvironmentFactory) processEngine).openEnvironment();
//    try {
//         ((ExecutionImpl)pInstance).createVariable("someString", "SomeString","string",true);
//     Session session = environment.get(Session.class);
//     Transaction tx  = session.beginTransaction();
//     session.update(pInstance);
//     tx.commit();
//    } finally {
//        environment.close();
//    }

While debugging I am able to see data in variable object, but it is not getting save in JBPM4_HIST_VAR table.
Can anyone help me?

Thanks in advance .
Regards,
Santosh
