Hello
I am trying to create a Task instances list with the pendings tasks for an
actor. I am not doing it from a JSF, so I think that I can't use
TaskIntanceList or TaskInstaceListFoType components.
Following DVD Store example, I think that I must use ManagedJbpmContext.
This is the process definition:
| ...
| <start-state name="Inicio">
| <transition name="peticion" to="Peticion"></transition>
| </start-state>
|
| <task-node name="Peticion">
| <task name="evaluarPeticion">
| <assignment actor-id="#{asignarTarea.getBibliotecario}"/>
| </task>
|
| <transition name="aceptar" to="Pedido"></transition>
| <transition name="cancelar" to="Eliminado"></transition>
| </task-node>
| ...
|
I would like to get a tasks list for type "evaluarPeticion" from a bean method.
At this momments, it is working with this code:
| @SuppressWarnings("unchecked")
| public void test() {
| AsignarTarea bibliotecario = new AsignarTarea();
|
| // JBPM Context
| JbpmContext context = ManagedJbpmContext.instance();
|
| // Taks for an actor
| TaskMgmtSession tms = context.getTaskMgmtSession();
|
| List<TaskInstance> taskInstances = (List<TaskInstance>) tms
| .findTaskInstances(bibliotecario.getBibliotecario());
|
| // Task filter
| for (Iterator<TaskInstance> itr=taskInstances.iterator();
itr.hasNext();) {
| TaskInstance taskInstance = itr.next();
|
| if (taskInstance.getName().equals("evaluarPeticion"))
|
System.out.println(taskInstance.getVariable("idPeticion"));
| }
|
| }
|
With this method I get all the information I am looking for and it is working
fine, but I think that this is not the best way to do it.
Looking at the DVD Store demo, it uses the context.getSession to create a query
and access to the information. Can I do somethig like that to get a task
instances list for an actor and for a type without manually iterate all the
task instances?
If I use context.getSession, I dont know how to implement a query to retrieve a
task list.
Thanks.
