Taks instances

[melampo]

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.

@In List<TaskInstance> taskInstanceList;

is valid.

And of course you could @In JbpmContext;

Ok, it works fine... thank you.

I had it working now with this query:

List<TaskInstance> ti = (List<TaskInstance>) context.getSession()
 .createQuery("select ti from org.jbpm.taskmgmt.exe.TaskInstance as ti where ti.actorId = :actorId and ti.end is null and ti.isCancelled = false and ti.name = :taskName")
 .setString("actorId", bibliotecario.getBibliotecario())
 .setString("taskName", "evaluarPeticion").list();

but i prefer your solution, injecting the taskInstanceList is just what I need.

Thanks again.
