Get the activity from the task

[frauke]

Hello everybody,

how can I retrieve the activity from a task?
I tried this way, but the activity of this execution is null, although the activityId has the expected value.

        Execution ex = processEngine.getRuntimeService()
            .createExecutionQuery()
            .executionId(task.getExecutionId())
            .singleResult();
        PvmActivity activity = ((ExecutionEntity) ex).getActivity(); // is null
        String actId = ((ExecutionEntity) ex).getActivityId(); // is not null
‍‍‍‍‍‍‍‍

The same code works with the process instance, but what I need is the currently active activity after branching with an exclusive gateway.
Is there an other way of getting the activity?

Best regards
Frauke

Hi,

seems like I found out by myself:

        Execution ex = m_processEngine.getRuntimeService()
            .createExecutionQuery()
            .executionId(task.getExecutionId())
            .singleResult();
        String actId = ((ExecutionEntity) ex).getActivityId();
        ProcessDefinitionImpl p = ((ExecutionEntity) m_processInstance)
            .getActivity()
            .getProcessDefinition();
        PvmActivity activity = p.findActivity(actId);
Ok, it may not look extremly elegant, but it works.
Still the other way would be easier…
