Typeahead.js: Suggestions not displaying

[benguela]

I have replicated the issue here
http://codepen.io/benguela/pen/epMMyo

In the field enter the letters

sco

bloodhound fetches suggestions but they are not displayed. if however you enter

scot

bloodhound fetches suggestions and they are displayed.
I have a workaround at the moment where in line 1724 of the typeahead bundle I changed

that._append(query, suggestions.slice(0, that.limit - rendered));

to

that._append(query, suggestions.slice(0, that.limit));

but this is not the correct solution.

I have the same issue.. looking forward for a correct solution.

moved

rendered += suggestions.length; 

to after the append

that._append(query, suggestions.slice(0, that.limit - rendered));

and it appears to work

function async(suggestions) {
                    suggestions = suggestions || [];
                    if (!canceled && rendered < that.limit) {
                        that.cancel = $.noop;
                        that._append(query, suggestions.slice(0, that.limit - rendered));
                        rendered += suggestions.length;
                        that.async && that.trigger("asyncReceived", query);
                    }
                }

@pew007 that worked, I updated my codepen to include my typeahead lib, I made that change and tested it.

Many thanks.

I've just fixed this same bug myself and have already submitted a pull request. It's because of the way that Array.slice interprets a positive "end" parameter. Here is the pull request. Until the request is merged, feel free to download copies from my branch. https://github.com/twitter/typeahead.js/pull/1416

+1, encountered this bug just now too.

[varunet]

+1, same issue can be replicated here
http://jsfiddle.net/varunet/4vk43jpp/

Either of the fix works for me

1. moving rendered line below that._append

that._append(query, suggestions.slice(0, that.limit - rendered));
rendered += suggestions.length;

or

1. modifying that._append

that._append(query, suggestions.slice(0, that.limit));

Currently, I will be moving on with option 1 for fix. Hope this gets fixed in next release.

@karlhorky Thanks for the link! The Foundation framework's documentation uses Typeahead and we've needed this fix :)
