I understand tht this is classified as WAI, but I still think it is worthy of being called a bug, because you don't have to do this with setblock, but with testforblock.
EDIT: Also, even using Paul's workaround, I still can't get the command to detect a furnace with coal in the fuel slot: /testforblock ~ ~+3 ~-1 furnace 4 {Items:[0:{Slot:1b,id:263s,Count:1b}]}
What is wrong?
Still in 1.7 pre release, I think. This is what I have to test for a furnace with coal in the fuel slot:
/testforblock ~1 ~4 ~-1 minecraft:furnace 4 {Items:{Slot:1,id:263}} Either a problem with my tags, a problem with this issue, or (most likely) both.
P.S. I would be great if the error could tell you specifically what NBT tag didn't match, to make debugging SOOOOOO much easier.
