Hi, i think the only way to end all tasks from the task-node is to kill them
(or cancel them) in the action of the timer.
I added the code:
TaskInstance ti= executionContext.getTaskInstance();
| //ti.end();
|
|
| Collection tasks =
executionContext.getTaskMgmtInstance().getUnfinishedTasks(token);
| Iterator taskItr = tasks.iterator();
| while(taskItr.hasNext()) {
| TaskInstance ti2 = (TaskInstance)taskItr.next();
| if (ti2!=ti) {if(!ti2.hasEnded()) ti2.cancel();}
| {ti.end();}
So it should cancel the other task of the node (there are 2, timer and the
other task that waits for the user's action) and end the timer one, but
althought all processes are "propery" ended, it informs of an error:
14:02:27,758 DEBUG [TaskInstance] completion of task 'send_order' results in

It seems that by doing cancel or end the token goes to the next node (end) and
in the cancellation or ending of the other task it tries again to move forward
the token... i don't know what else to try. :(
