Due to this bug: http://bugs.jquery.com/ticket/11921
I need to upgrade my jquery-ui
When I look in development at app/assets/javascripts I see this:
but no jquery-ui
Nothing in public as we don’t compile assets in development.
app/assets/javascripts/application.js has this:
//= require jquery
//= require jquery_ujs
// Comment about stuff
//= require jquery-ui
//= require LISA
//= require jquery.rest
//= require jquery.autoSuggest.packed
Ruby 1.9.3-p194, rails 3.2.8 (being upgraded from rails 3.2.6)

Did you check
lib/assets/javascriptsandvendor/assets/javascriptstoo?Really, it should be in the
vendorfolder. It is a “vendored” jQuery plugin because a 3rd party authored it.Also, as @Amar mentioned in his comment, it could also be installed via a gem.
