Unfortunately its not the ghost opening, the ghost opening is another "set" of doors (lines on plan) inside the others. I did open the object and just couldn't find where this secondary door is described.
The ghost opening actually works the way (I believe) the secondary door should in that you can set the angle and the linetype in the parameters already in the door settings. Unfortunately turing it on for the double acting door gives you four doors in plan. I have even tried the ghost door in a "regular" door but it won't accept negative values for the angle which is what's needed as positive values place it on the same side as the primary door.
Thanks anyway.
