Endereyes unplaceable in adventure mode

What are the exact commands you used?

/give @a minecraft:ender_eye 1 0 {CanPlaceOn:["end_portal_frame"]}

I can see the outline of the end_portal_frame but I can't place the ender eye in the portal.

I also tried
/give @a minecraft:ender_eye 1 0 {CanDestroy:["end_portal_frame"]}

and that does not work either.

Confirmed without any command

no effect in 07a too

still a bug in 08a

Confirmed for 14w19a.

Confirmed for 14w21b. Just a note: you can place the ender eye into a frame as long as there is a frame adjacent to the target (does not matter if the adjacent one is filled). This works in any direction, so the frames could be on top of one another.

Sometimes, we can place them but it's rare..

Has this been fixed?... I have an adventure map that uses end portal frames as a way to open doors and I am having trouble getting it to work. These are good for doors that people pass back through because they cant pull the eye of ender back out of it unlike a juke box and a disc.

Fixed for 1.8:

/give @p ender_eye 64 0 {CanPlaceOn:[end_portal_frame]}
