MC-117331Tripwire Hooks and Ladders can be placed on blocks that they should not be able to
Tripwire hooks are now placeable on many things that they should not be able to be placed on including "glassy blocks" such as glass, glowstone, sea lanterns, ice, and more, such as leaves and pistons. This is relative to what they were placeable on in prior versions, which is assumed to be the originally intended behavior. In prior versions, they shared the same placing and valid attachment requirements as redstone components that attached to the sides of blocks such as levers and buttons, unless other components are going to be able to attach to such things as well going forward, it would be confusing to have some of these attach to certain blocks and have other things not attach to the same blocks due to seemingly arbitrary conditions.
A list of blocks that tripwire hooks and ladders are attaching to that are erroneous according to precedence in previous versions: glass, stained glass, ice, frosted ice, leaves pistons (full sides only, when extended only the back is "valid"), the face of piston heads, glowstone, sea laterns, shulker boxes, beacons, and cauldrons.

The fix for MC-117331 seems to have been incomplete. Ladders can still be placed on improper blocks, as long as a solid block also borders the ladder. The ladder does not update and pop off when the solid blocks are removed.
I also find it strange that torches can be placed on the sides of observers but that other redstone components can not be and that redstone components can be placed on top of pistons and observers regardless of their orientation but not on the other sides when rotated differently but those details have precedence and may not be bugs.
Could you please create a list of blocks tripwire hooks and ladders (and vines?) can be placed on but should not.
I suggest creating a new report for that unless there is already one (was not able to find one though).
The vine behavior has not changed since 1.11.2. I didn't check prior versions but I assumed that was likely the intended behavior since they have to attach to leaves and other things. I also assumed that the difference in side attachment for torches and for redstone components might not be a bug because no one had mentioned it since we got observers and in all other aspects, components attached to observers the same as they did to pistons.
Ultimately that ties in with whether or not all blocks that "hang on" or attach to other blocks such as redstone components, ladders and torches should be able to attach to the sides and undersides of pistons and observers in the first place as they were not able to previously. That being said, components attaching to the tops of pistons was added so why not the sides and bottom as well?
Please still add a list of all blocks ladders and tripwire hooks can be placed on to the report.
I am going to report then that you can place torches on the side of observers and redstone blocks.
I guess you didn't see my edit, I did add a list of blocks that they are currently attaching to that they should not be after some more experimentation.
As far as torches attaching to redstone blocks, I'd check some of the older versions to see if that might actually have been intended behavior. I'm pretty sure they always have been able to attach to them. If anything, I'm all for things being able to attach to more blocks, so long as it's consistent and makes some small amount of logical sense.
Oh sorry yes I overlooked the list.
In Pre-Release 3, ladders can still be placed on improper blocks if a solid block is beside the ladder. Removing the solid blocks does not cause the ladder to update and fall off.
Zed Ontargs, please create a new ticket (if it wasn't done already)
Done, see
