Default Two parallel active task sequences

Hi everybody,

related to my other thread (https://www.flexsim.com/community/fo...ead.php?t=3082)
I experimented with task sequences and preempting.
During experimenting I noticed that my task executer does have two active task
sequences in its tree like shown in the attachement.

Until now, I always thought a TE can have at most one active TS at any time.
And also the documentation says "At any given time in a simulation, a TaskExecuter can
have one active task sequence as well as a queue of waiting task sequences."

Can someone help me understanding the two active tasks in the screenshot?
Do I have to interpret the two "ACTIVE >>>" labels differently?


Thanks
Paul

From what trigger are you inserting the new task sequence?

Wherever it is, you might try sending a delayed message in 0 time and creating the new task sequence from there instead.

The problem is probably that you are creating a task from a trigger that doesn’t expect that task sequences will be created while executing that trigger, and then the built-in logic of the object that called that trigger is then doing something to the original task sequence that causes it to continue executing and get put back into the activetasksequence.

I don’t know for sure if that is the problem, but that’s my hunch. Try using a delayed message instead to see if that fixes it.
