RAILS_GROUPS=assets
assets:precompile
Though the Pull request has been merged into AA by now, you will still have this problem if you work with the latest release of AA. I don't like to force JQuery-rails down to version 2.3.0 so here's an alternative solution to the problem:
In the active_admin.js file replace
//= require active_admin/base
with
//= require jquery
//= require jquery_ujs
//= require jquery.ui.core
//= require jquery.ui.widget
//= require jquery.ui.datepicker
//= require active_admin/application
kudos to Fred for providing that solution here.
