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!
