Weighted Pressure Plate on top of Hoppers won't pass Items
related to MC-6808 (https://mojang.atlassian.net/browse/MC-7230)
My Plan:
A Golden Weighted Pressure Plate act as a Door opener.
Put items on top and a door opens.
To reset the system I have to remove the items somehow from the Plate. I tried a Hopper to suck the items when the exact amount activate the Plate.
Bug:
In snapshot 13w02a switches on top of hoppers had no effect of the hopper,
but in 13w02b this was fixed
But now if you place a Weighted Pressure Plate on top of a disabled Hopper, you can't suck the items from the Plate into the hopper, when you cut the power.
Because two mechanics block each other; Pressure Plate give a signal by one item, hopper accept turn-off signal from the top.

Intended behavior. The pressure plate is powering the hopper, which in turn stops taking in items.

I dont think this is a bug. Even though I think a mechanism like your's should be possible, because else the weighted pressureplates are a little bit useless, as you have to pick up all the items yourself...
Moritz is right, I almost made a similar mistake. Weighted pressure plates produce various signal strengths depending on how many items their are; both gold and iron react to any number of blocks placed on them, even a single block. However the signal strength is only one until you place enough blocks for it to increase. This is unfortunate, too, as I was planning on making something that required this mechanic.
Works as intended, redstone inputs will block items going in or through a hopper.
will make the pressure plate useless
