I have an ItemStack, that has only one capability - SocketCapability. When i'm trying to check/get it, i'm getting false/null.

But if I call methods right on it's provider, all is fine

 

	public void preInit() {
		CapabilityManager.INSTANCE.register(ISocketCapability.class, new SocketCapabilityStorage(), new SocketCapabilityFactory());
		GameRegistry.registerTileEntity(TileInlayTable.class, ModBlocks.INLAY_TABLE.getRegistryName());//TODO universal tileEntity registing
	}

public class SocketCapabilityFactory implements Callable<SocketCapability> {
	@Override
	public SocketCapability call() throws Exception {
		return new SocketCapability();
	}
}

 

public class SocketCapabilityProvider implements ICapabilitySerializable<NBTBase> {

	@CapabilityInject(ISocketCapability.class)
	public static final Capability<ISocketCapability> SOCKET_CAPABILITY = null;

	private ISocketCapability instance = SOCKET_CAPABILITY.getDefaultInstance();

	@Override
	public boolean hasCapability(@Nonnull Capability<?> capability, @Nullable EnumFacing facing) {
		return capability == SOCKET_CAPABILITY;
	}

	@Nullable
	@Override
	public <T> T getCapability(@Nonnull Capability<T> capability, @Nullable EnumFacing facing) {
		return capability == SOCKET_CAPABILITY ? SOCKET_CAPABILITY.cast(instance) : null;
	}

	@Override
	public NBTBase serializeNBT() {
		return SOCKET_CAPABILITY.getStorage().writeNBT(SOCKET_CAPABILITY, instance, null);
	}

	@Override
	public void deserializeNBT(NBTBase nbt) {
		SOCKET_CAPABILITY.getStorage().readNBT(SOCKET_CAPABILITY, instance, null, nbt);
	}
}

public class SocketCapabilityStorage implements Capability.IStorage<ISocketCapability> {
	@Nullable
	@Override
	public NBTBase writeNBT(Capability<ISocketCapability> capability, ISocketCapability instance, EnumFacing side) {
		NBTTagCompound compound = new NBTTagCompound();
		NBTTagList list = new NBTTagList();
		if (instance.getSocketsCount() > 0) {
			for (Socket socket : instance.getSockets()) {
				list.appendTag(socket.serializeNBT());
			}
		}
		compound.setTag("sockets", list);
		return compound;
	}

	@Override
	public void readNBT(Capability<ISocketCapability> capability, ISocketCapability instance, EnumFacing side, NBTBase nbt) {
		NBTTagList list = ((NBTTagCompound) nbt).getTagList("sockets", 10);
		if (list.isEmpty()) {
			instance.setSockets(new Socket[0]);
		} else {
			Socket[] sockets = new Socket[list.tagCount()];
			for (int i = 0; i < list.tagCount(); i++) {
				sockets[i] = new Socket(list.getCompoundTagAt(i));
			}
			instance.setSockets(sockets);
		}
	}

This is broken. You need to use a ResourceLocation that represents your capability provider, not the stack's item's name.

Fixed it, but it didn't fix the bug. And bug only when I shift-click, when taking item in regular way, all is ok.

Figured out, that the problem is that on successfull getting item by shift-click, itemStack passed into onTake is empty. What is the right way to change item, before taking it?
