jBPM-4.4 Unable to save Process Variable History

[santoshsingh]

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
