Get idle period for a task

[arne]

Hi there,

I have been looking for a way to determine the time a task has been idle before it has been claimed by a candidate user?

If I have a process with two sequential <UserTask/> definitions. Both tasks have the potential owner set to a user(xyz). When I now deploy and start the process the start time for the first task is set directly and not when a candidate user claims the task. And that´s what I define to be the "idle time" of a task.

In the project I am working on currently we define the following:

running time = idle time + process time

running time: the total duration
idle time: starting after previous task has completed
process time: time it took a user to complete the task (from "claim" to "complete")

How can I get this figure for tasks? I have not found any way through the API?

I´d be glad if somebody could help!

Thanks in advance,
Arne

There is no such thing built in by default in activiti. What you could do, is add a task-listener to your tasks which gets triggered on event "assignement". In this listener, you can set the current time in a task-local variable (delegateTask.setVariableLocal()).

When you task is completed (perhaps in another tasklistener) you have start-time, time that task was claimed and end time. Alternatively, if you wet your history level high enough,  the task-local variables (and task) will be available in the history, so you can fetch the times for completed tasks.

Thanks Frederik,

used the TaskListeners… but from there we have decided to store a 'task history' in a separate table.
