[jboss-user] [JBoss jBPM] - process variables out of session

Hi, I use variables (business objects) in ActionHandler

public class Task_ABC implements ActionHandler{

	public void execute(ExecutionContext executionContext) throws Exception {
		ContextInstance c = executionContext.getProcessInstance().getContextInstance();
		Abc abc= (Abc) c.getVariable("abc");
                .... do something ...

Problem is that this variables are not registered in session, if variable has an association and I use it, I get an exception. But if I have variable class has only primitive attributes (String, BigDecimal..) it works perfectly. Workaround is to declare all association in Hibernate as lazy="false" what I don't want. But really interesting is, that if I change value in variable that it will be stored in db. That means that jbpm will register variables in Hibernate session but later and I don't know when.

I don't use any special workflow configuration. This is snip set from my workflow interface:

public class WorkflowService extends HibernateDaoSupport implements IWorkflowService {

	private static JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance();

	public void startWorkflow(Workflow workflow, Map<String, Object> variables) {
		JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
		try {
			 ProcessInstance processInstance = jbpmContext.newProcessInstanceForUpdate(workflow.getFullName());
		} finally {
