Failure to properly use "mod.addSmeltingRecipeFor" and "mod.addFuelFor"

[Samantha Meredith]

I added a custom furnace that uses its own designated recipe and fuel list, set the tile entity for the furnace to use the list "juicer" and then assigned some smelting recipes and fuels for "juicer" However, the smelting recipes were ignored, and the fuel specifically set for juicer instead registered as vanilla, even though I wrote it as mod.addFuelFor("juicer", etc, etc); Is this a bug with the build I have, which is the very latest one, or is the documentation out of date?
