Hi, I am having the same issue.. I am trying with the basic example and did not work :(
Any suggestion?

Had the same issue. While debugging recognize that data was wrong cached.
window.localStorage.clear()
fixed the issue.
when it can't find data in cache it goes to fetch functionality and then it creates correct data structure.

Also be sure that
datumTokenizer
and
queryTokenizer

is initilized like a function, for example:

datumTokenizer: function (data) {
var wordToken = A.Bloodhound.tokenizers.whitespace(data.name);
return wordToken;
},
queryTokenizer: function (searchStr) {
return A.Bloodhound.tokenizers.nonword(searchStr);
},
where arguments:
data - it's row with column 'name'
searchStr - it's string which were typed by user in a control

for the newbeies like me; to make bloodhound work standalone...

$(document).ready(function() {

/ / add states var here (search data)
var states = ['Alabama', 'Chicago',etc ]

// constructs the suggestion engine
var states = new Bloodhound({
datumTokenizer: Bloodhound.tokenizers.whitespace,
queryTokenizer: Bloodhound.tokenizers.whitespace,
// states is an array of state names defined in "The Basics"
local: states
});

$('#bloodhound .typeahead').typeahead({
hint: true,
highlight: true,
minLength: 1
},
{
name: 'states',
source: states
});
});
