Turn Redstone Torch off?

I'm trying to turn a redstone torch off if a certain condition isn't met. I got it to turn off but when you place redstone wire next to it the torch turns back on. I have a scheduler event that checks certain torches, if a condition is not met the torch will be turned off.

Code:

Block above_block = block.getWorld().getBlockAt((int) entry.getX(), (int) entry.getY() + 1, (int) entry.getZ());
above_block.setType(Material.REDSTONE_TORCH_OFF);
 	        	}

Here's the code that I'm running to turn the torch off. This is in a method that updates ever second. Anyway to keep this torch turned off?

 

add the torch to a hashmap of torches you don't want to turn on, and add a BlockPhysicsEvent. Then just do this:

Code:

if(hashmapname.containsKey(event.getBlock())
{
event.setCancelled(true);
}

 

Actually, after testing, cancelling the BlockPhysicsEvent seems ineffective. However, setting the torch to the off state on a physics check works just fine.
