Issue with Tabs/Cookie

Reported by: Eagle Owned by:

The Tabs component supports remembering which tab was last made active through the use of cookies and the jQuery Cookie plugin. However, it appears that the Tabs code does not actually invokve the Cookie plugin in the correct fashion.

The cookie plugin for reading and writing cookies works off the basis that:

  • If a name and value are passed, it creates a cookie with those

values (and any other parameters).

  • If only a name is passed, the corresponding cookie is read if


  • If a name and null are passed, it expires the named cookie.

The trick is that the cookie plugin uses typeof to determine whether a value was supplied, even if it is a null:

jQuery.cookie = function(name, value, options) {

if (typeof value != 'undefined') { // name and value given, set


The call from jQuery UI to the plugin, however, provides null for the value parameter even when attempting to read back the value, meaning value is not undefined but rather null, and thus invoking the expiry mechanism.
