MC-27484Hanging Entities (e.g. Item Frames, Paintings, and LeashKnots) cannot be spawned
What I expected to happen:
A custom spawner would be able to spawn hanging entities (such as ItemFrame and LeashKnot) in the world.
What actually happened:
Although the spawner appears to spawn (its particles go off), the entity does not appear anywhere in the world. This happens regardless of what its position, motion, rotation, and tile tags are set to - no combination makes the entity appear in the desired (or any) location.
Steps to Reproduce:
- Import one of the attached schematics into your world.
- Observe that, although an entity spins in the spawner cage, it's never spawned. This is the case even when its spawn particles (a burst of extra flames) go off.

Like the reporter said it might be caused because the game can't render it. This makes sense as changing the TileX, TileY or TileZ value causes Minecart to teleport the ItemFrame/Painting to this position.
One thing interesting to note is that trying to set TileX, TileY or TileZ manually results in a crash of the (internal) server.
Client crash report (no TileX, TileY and TileZ)

This remains true for the new /summon command just as it did for spawners. It gives you the option to summon these entities, and claims it succeeded, but the entity never appears in the world.
Is this still a concern in the current Minecraft version 1.7.2 / Launcher version 1.3.4 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
For LeashKnots and Item Frames, this appears to be fixed. Paintings I can't test, as they have a separate crash bug. However, LeashKnots will always spawn at 0,0,0 and are not saved. I suppose that's a separate issue, however, so this can be closed.
