[SOLVED] Crash on finishing smelting

[magusapollo]

SOLVED: Passing an int to the first argument of the ItemStack constructor was incorrect. It needed to be an actual item.

 

I'm attempting to add some ores and ingots, and most of the functionality appears to work. The furnace recipes I can initiate, but when smelting is finished, I get a crash involving a NullPointerException and ItemStacks. The research I've done makes it sound like it might be something to do with the metadata or initialization of the items, but my attempts to fiddle with those have proved fruitless.

 

I'm attempting to use metadata to represent some of the categories of items (ore and ingots so far), so those are located in their respective block and item classes.

 

Here's the ForgeModLoader-client-0 log: http://paste.minecraftforge.net/view/4f294e03

 

And here're the recipes, ingot code, and mod files. I'd be happy to provide any additional information.
