Operator State Process Flow

I'm having some issues setting custom states in process flow for my operator. I tried following some previous threads to no avail. In my Drain Belt 1 Filling box, I'm attempting to use a custom task to have my operator shown as "busy" during a filling operation taking place by a combiner. I got that far, but further down the line the same operator won't complete the next load task. I set a custom code to idle the operator, but that didn't seem to free him up either.

On the Drain Belt 2 box I attempted using 2 custom codes to set the operator state while filling, and that didn't work at all.

I'm just curious what the best solution is to manually set my operators state while "waiting for an event"?

Hi @Jimmy G2,

the operator does not load the item after the process finishes because he is still stuck in the "Utilize" task. The state and the task(-sequence) of a task executer are independent of each other. Starting a task will in most cases set the corresponding state, but changing the state won't stop the task. To have the operator stop the custom utilize task, use the "freeoperator()" command.

Your other solution of setting the state in a custom code activity also works. You have to put a delay (can be 0-seconds, devs call these "Breathe") inbetween finishing the last task and setting the state though. This makes sure that the operator first returns to the idle state and then gets set to a different state and not the other way around.
