Signs no longer have a specific isEdiable state, the entire API in this regard needs updating/deprecation. The boolean field is completely gone, replaced by a uuid (which will need a new setEditingPlayer(UUID) method on the Sign interface), and the current upstream implementation of setEdiable simply flips the is_waxed state. This patch is hence not needed as it neither allows editing (which will be redone in a later patch) nor is required to copy the is_waxed boolean flag as it lives in the signs compound tag and is covered by applyTo.

Subject: [PATCH] Break redstone on top of trap doors early
|
|
|
|
This logic hooks into the neighbour update which should be invoked
|
|
as a result of redstone powering the trap door.
