[1.12.2] Block with property boolean error

[American2050]

I wonder what I'm doing wrong here. Trying to register a block with a property boolean for "Powered" but I get an error and not sure what causes it.

 

I have:

 

public class BlockZand extends GenericModBlockFalling implements IHasModel{
	
	public static final PropertyBool POWERED = PropertyBool.create("powered");
	
	public BlockZand(Material materialIn, String name) {
		super(materialIn, name);
		this.setUnlocalizedName(ModInfo.MODID + ":" + name);
		this.setHardness(1.0F);
		this.setSoundType(SoundType.SAND);
		this.setTickRandomly(true);
		this.setLightLevel(5F);
		
		this.setDefaultState(this.blockState.getBaseState().withProperty(POWERED, Boolean.valueOf(false)));
		
		ModBlocks.BLOCKS.add(this);
		ModItems.ITEMS.add(new ItemBlock(this).setRegistryName(this.getRegistryName()));
	}

 

The error:

The registration:

 

	@SubscribeEvent
	public static void onBlockRegister(RegistryEvent.Register<Block> event){
		event.getRegistry().registerAll(ModBlocks.BLOCKS.toArray(new Block[0]));
	}

 

I guess my problem is that I'm either extending wrong classes or trying to set the default value at the wrong time?

 

Thanks for your help.
