3D Item wont render in Inventory

[Thornack]

I have made a custom 3D ball and wish to render it in my inventory. It is an item that throws like the snowball but in the ItemRenderBall.java class the following switch statement wants to return an entity but when I replace null with (Entity) data[1] I get an out of bounds error.

 

problem code

switch (type) {
	case INVENTORY:
		GL11.glPushMatrix();
		// rotates the item and translates the item
		GL11.glRotatef(0, 0, 0, 1);
		GL11.glRotatef(0, 0, 1, 0);
		GL11.glRotatef(180, 1, 0, 0);
		GL11.glTranslatef(0f, 0f, 0f);
		GL11.glScalef(0.5F, 0.5F, 0.5F);
		Minecraft.getMinecraft().renderEngine.bindTexture(this.itemBallTexture);
		// renders the item
		modelBall.render(null, 0.0f, 0.0f, 0.0f, 0.0f,
				0.0f, 0.0225f);
		GL11.glPopMatrix();
	default:
		break;
	}
