I'd like to have an operator bring an object from a queue to an "Item to Fluid" object each time the 'Item to Fluid" goes empty. I am able to do this in the 3D model pretty simply, but want to do it in a Process Flow so that I can introduce a delay.
I've played with the onEmpty trigger and a sendMessage, but haven't been able to make them all work together yet. I would welcome any advice!
