Set Spawner's NBT Data Based on Data from a Mob

I made several stabs at this earlier... I can't seem to figure it out.

PHP:

public class NBTEvents implements Listener{
@EventHandler
public void clickEntity(PlayerInteractEntityEvent event){
Player player = event.getPlayer();
 
if (PlayerSession.getEnabled(player) == true){
PlayerSession.setClickState(player, (byte)1);
CraftEntity ce = (CraftEntity)event.getRightClicked();
if (ce instanceof CraftLivingEntity){
CraftLivingEntity ent = (CraftLivingEntity)ce;
NBTTagCompound com = new NBTTagCompound();
ent.getHandle().a(com);
 
PlayerSession.setPlayerStored(player, com);
player.sendMessage(ChatColor.BLUE + "You have clicked on an entity. Now right-click a spawner!");
}
}
}
@EventHandler
public void clickSpawner(PlayerInteractEvent event){
Player player = event.getPlayer();
if (PlayerSession.getClickState(player) == 1){
if (PlayerSession.getPlayerStored(player) != null){
if (event.getClickedBlock() != null){
if (event.getClickedBlock().getType().equals(Material.getMaterial(52))){
Location loc = event.getClickedBlock().getLocation();
CraftWorld cw = ((CraftWorld)event.getClickedBlock().getWorld());
TileEntity te = cw.getHandle().getTileEntity(loc.getBlockX(),loc.getBlockY(),loc.getBlockZ());
NBTTagCompound tag = new NBTTagCompound();
te.b(tag);
 
tag.setCompound("SpawnData", PlayerSession.getPlayerStored(player));
 
te.a(tag);
 
player.sendMessage(ChatColor.YELLOW + "Applied the stored nbt tag to the spawner!");
PlayerSession.setEnabled(player, false);
PlayerSession.setClickState(player, (byte)0);
}
}
}
}
}
}


I believe this is what you should need.
Basically, my problem is that everything fires, but then the spawner still spawns what it was before (in this case, pigs). When I restart the server, an error is thrown and the spawner removed from the map. (So I assume that the NBT data was corrupted).
Any ideas? I can't seem to get it to work.

 

You can use the CreatureSpawner BlockState (http://jd.bukkit.org/rb/apidocs/org/bukkit/block/CreatureSpawner.html). Check if block.getState() instanceof CreatureSpawner, cast, then set the spawned type.

 

chasechocolate will test that out, thanks Not sure if the NBT will work though.
