The variable "terms" is null on line 29, which is why you are getting NullPointerException. > query.setRequestHandler("terms"); One possible problem is setting the request handler to "terms" ... chances are that this should be "/terms" instead. Handler names in your config will most likely start with a forward slash, because if they don't, a typical example config in version 3.6 and later doesn't allow any way for them to be used. Since 3.6, "handleSelect" is set to false in all examples, and it should be left at false. Thanks, Shawn
