jQuery UI Tabs Plugin Broke
- by Warren J Thompson
We are using the jquery ui tabs arrow plugin from this fiddle: http://jsfiddle.net/dECtZ/282/, but like many plugins, it breaks with the latest version of jQuery. We were able to get the csscur to work, but still get the following error in the jquery core (line 353):
Uncaught TypeError: Cannot assign to read only property 'length' of function (e,t){if(!this._createWidget)return new o(e,t);arguments.length&&this._createWidget(e,t)}
Code is as follows:
(function($, undefined) {

_super = {
_create: tabs._create,
_destroy: tabs._destroy,
_update: tabs._update
};
$.xui.tabs = $.extend(tabs, {
options: $.extend({}, tabs.options, {
scrollable: false,
changeOnScroll: false,
closable: false,
resizable: false,
resizeHandles: "e,s,se"
}),
_create: function() {
var self = this,
o = self.options;
_super._create.apply(self);
if (o.scrollable) {
self.element.addClass("ui-tabs-scrollable");
