[1.8.9] Tile Entity Missing a Mapping

[TheGoldCrayon]

I was recently able to make a tile entity, but I seem to be having a problem with getting its contents to save. The problem seems to lie with the writeToNBT method. I am able to put items into my tile entity using a hopper, but whenever I save and quit, and then re-enter the world, they never get saved into the tile entity. Also, the console throws this out to me:

I have seen several issues similar to this online, but each one says that the solution is that someone forgot to register the tile entity. However, I have my tile entity registered. I register them in here, my TileEntities class:

And then I call that method in my CommonProxy class:

I'm sure it's something simple that I'm overlooking, but any help would be appreciated.

Do you ever call

CommonProxy#preInit

? Set a breakpoint in

TileEntities.init

and run Minecraft in debug mode, is the breakpoint hit?

 

In future, please select the appropriate syntax highlighting when posting code using sites like Pastebin/Gist.

Thank you. That was my problem. I never actually called that method.
