How to detect if a unit has "no order"?

Lets say you have a map with a unitspawn for the computer that attacks something, somewhat like AoS. Now also heroes spawn there.
The problem is, if heroes cast active abilities they do not remember their last command and just stay there.

Now I want a trigger that gives units with stop order or NO ORDER some new orders. The problem is, how can i detect if a unit has NO ORDER at all?

use the search function, already been answered.

I was searching and didnt find an answer.

okay its very simple...

Event:

Unit - A unit owned by Player X Is issued an order with no target

A:

Unit - Order (Ordered unit) to "UR ACTION HERE"

Chemo, I don't think that will work...

Try this putting this as condition, Bloodlust -- (Current order of (YOUR UNIT)) Equal to (Order(stop))

it does work perfectly in my map...
so no need to worry

ok i will try if it works this evening, thanks
