Cuando trato de ejecutar una tarea manual en el Bonita desde el eclipse, me sale el siguiente error.

Mi codigo fuente es:

boolean resolved = false;
String result = "";

APISession apisession = bpmService.createLogin(username, password);

pendingTasks.clear();
pendingTasks = processAPI.getPendingHumanTaskInstances(apiSession.getUserId(), 0, 30, null);

for (Iterator<HumanTaskInstance> i = pendingTasks.iterator(); i.hasNext();) {
    HumanTaskInstance item = i.next();
    if (item.getRootContainerId() == request.getInstanceId()) {
        taskid = item.getId();
        processAPI.updateActivityInstanceVariables(taskid,    request.getVariables());

        resolved = true;
        break;
    }
}

Mi versión del Bonita en Maven es 7.8.4 y utilizo Eclipse.

¿Tienen alguna idea de que puede ser?

Gracias.

Cómo contado en el Bonita bug tracker BBPMC-553 que abriste, el problema parece relacionado con la comprensión de la manera de transmitir los datos del lado del cliente (tu aplicación Java) hasta las variables de negocio de Bonita a través del contrato, usando operaciones y la metodología API.

Para entrar en más detalles, te dejo referirte por favor a la respuesta de mi compañero en el BBPMC-553.

Hola que tal, ya pude resolver este problema reemplazando el método “updateActivityInstanceVariables” por “executeUserTask(userId, taskid, listVariablesSerializable)”.

Gracias.

Hola Ingrid,

Vamos a contestar tu pregunta. Pero antes de todo, te queria avisar que voy a remover una de tus preguntas, porque lo has duplicado en íngles y español.
Que idioma te parece más sencillo? Gracias

Hola, mas fácil podría ser en español?

Sin problema, contestamos pronto y de momento voy a remover la version en ingles.
