Using Directional.setFacingDirection doesn't turn the block

I have been working on this for a while and I can't seem to get why the Block isn't turning. Here is the code I am using.

Code:java

public BlockChange draw(World w, int x, int y, int z){
        Block b = w.getBlockAt(x + pt.getX(), y + pt.getY(), z + pt.getZ());
        BlockChange change  = new BlockChange(new BlockRef(new Point3D(x + pt.getX(), y + pt.getY(), z + pt.getZ()), b));
        b.setType(type);
        b.setData(data);
        if(b.getState().getData() instanceof Directional){
            Bukkit.broadcastMessage("Applying Direction " + face.toString() + "...");
            ((Directional)b.getState().getData()).setFacingDirection(face);
            Bukkit.broadcastMessage("Block is Facing " + ((Directional)b.getState().getData()).getFacing());
        }
        return change;
    }

I get an output of

Applying Direction NORTH...
Block is Facing SOUTH

Editing the return value of "block.getState().getData()" doesn't edit the BlockState
You have to set MaterialData with "block.getState().setData(MaterialData data)"
The after that, you might have to use "block.getState().update(true);"

 

So I have to get the data and store it in a instance. Then set the state data to the instance?
And then force the update.

Code:java

Bukkit.broadcastMessage("Applying Direction " + face.toString() + "...");
Directional d = (Directional)b.getState().getData();
d.setFacingDirection(face);
b.getState().setData((MaterialData) d);
b.getState().update(true);
Bukkit.broadcastMessage("Block is Facing " + ((Directional)b.getState().getData()).getFacing());

Same output.

I use:

Code:

block.setData((byte) value);

Data values: http://www.minecraftwiki.net/wiki/Data_values

 

Won't doing that override whatever other data I have already on the block?
