To have a task executer plot a course around another inactive task executor it has to be added as a dynamic barrier during the path calculation.

@anthony.johnson demonstrated this functionality in his KIVA system example model.

Essentially you react to a task executer triggering the path calculation with an event triggered source and return an array of objects that should act as barriers during the calculation.

I adjusted your model to return all task executers that are currently in an idle state.

Thanks Felix. A follow up question, do you know where I can understand the sequence of events such as calculate path, navigate path etc ?
