YOU CAN NOT USE THAT LINK..
AS THE BACKING TO THAT PAGE IS STILL 1.9.2
DO THE SAME THING BUT WITH 1.10.0
NOTE - THE DECRIPTION IS MISSING on 1.10.0 so it appears to work..... but it is NOT
THIS HAS NOW MADE ITS WAY TO THE FINAL AS WELL
ie for those not getting this try and read the description in the auto complete when you type say "j", its will show Java, and the description will be missing.... which is the point of the custom, demo...
please open the custom-data demo example!!!!
P.S. sorry for the red and bold, but i tried to type this out twice last night and both times it said it was successful, but both times nothing was posted.
