I have a laptop that I frequently dock/undock. My laptop in on right of my principal screen when docked.
I'm using the configuration: "edge binding" "flip desktop in Direction..." for each four direction.
Each time I connect or disconnect the external screen, none of the edge action works. They come back to life after an enlightenement restart (ctrl+alt+end).
Version info (efl/enlightenment compiled from git):
% pacman -Q | grep efl
