[xwiki-users] jQuery UI components in XWiki

Hi, I'm experimenting with including some jQuery UI elements into some wiki pages using XWiki 7.1. As a test, I've been trying to get the spinner example from http://api.jqueryui.com/spinner/ to work: I have constructed a minimal page, with content body: {{velocity}} {{html}} <input id="spinner"> {{/html}} {{/velocity}} And for the page I've added an objects of type XWiki.JavaScriptExtension containing code: require(['jquery'], function($) { $( "#spinner" ).spinner(); }); However, viewing the page yields an error TypeError: a(...).spinner is not a function "require(["jquery"],function(a){a("#spinner").spinner()});" So it looks as though the spinner UI code is missing, so I'm guessing I need to include the jQuery UI library somehow. I'm a little confused because there is a jquery-ui-1.11.1.jar file in /usr/lib/xwiki/WEB-INF/lib/ which led me to believe that it was already bundled with XWiki. http://platform.xwiki.org/xwiki/bin/view/DevGuide/FrontendResources says "Prototype is the only JavaScript library that is systematically shipped with any wiki page in XWiki." But it's a bit old. Any pointers? Thanks, Bryn
