I was using /setblock in chat to get the cords right. After I did I pasted it into command block.

setblock 46 3 -44  minecraft:redstone_block

What I expected to happen was...:
the specified block would go to redstone

What actually happened was...:
The block didn't change so looked into command block for the error.
*Note I tried other id's before posting this.

Steps to Reproduce:
1. enter "setblock x y z minecraft:<blockname>" into a command block
2. Activate command block
3. Look at command block bottom line for "There is no such item with ID"
