Okay, I have a custom crop that I do something special when it finishes growing.  So in 1.7.10 I had a tile entity associated with the block and the tile entity checked for finished growing and performed the code.

 

The problem I'm having in 1.8 is that in the grow() method of my crop block class I use the setBlockState() method to update the growth.  This is copied from the vanilla BlockCrop.  However, I noticed that the tile entity gets recreated every time the setBlockState() method is called.  This is a problem since I have other fields in the tile entity that are supposed to be preserved over time.

 

I am determining that it is recreating a tile entity by putting a console statement in the createTileEntity() method in my block class.

 

The weird thing is that the Block code seems to be correct -- it checks for a TileEntity before creating it:

                if (block.hasTileEntity(p_177436_2_))
                {
                    tileentity = this.func_177424_a(p_177436_1_, Chunk.EnumCreateEntityType.CHECK);

                    if (tileentity == null)
                    {
                        tileentity = block.createTileEntity(this.worldObj, p_177436_2_);
                        this.worldObj.setTileEntity(p_177436_1_, tileentity);
                    }

                    if (tileentity != null)
                    {
                        tileentity.updateContainingBlockInfo();
                    }
                }

 

So my question is -- how can you change a block's state without regenerating the tile entity?

Okay, that seems to have solved it.  Now calls updateContainingBlockInfo() as expected.

 

I'm not sure why it worked for me in 1.7.10 though if you say it works the same.  Oh well.  Thanks!
