CMDHELPER-2836 - Reported by CyaNox

Simple test code:

bind(pressure_plate_activated, null, null, @e,
  console(@e)
)

Comment by LadyCailin

This isn't supported, as this is intended for when a player steps on a normal pressure plate. This can be added as a feature request, but this isn't a bug.

Comment by PseudoKnight

Pressure plate types are not filtered from the bukkit event, thus bukkit does not trigger a physical interact event with these pressure plates yet. When they add this support, CH should automatically support it.

BTW, redstone_ore, tripwire, and stomping farmland also triggers this event, which is cool. :) I guess this means the CH event name is a little misleading, (along with the fact that other entities do not trigger this event, as expressed in the other issue) though I like its functionality.
