Accordion: option animated true causes JavaScript error

[rdworth]

The accordion option 'animated' is documented as supporting boolean data type. animated: false works, but animated: true does not.

Expected animated: true enables animation with 'slide' (the documented default animation)

Actual animated: true causes a JavaScript error when a header is clicked.

jQuery.easing[this.options.easing || (jQuery.easing.swing ? "swing" : "linear")] is not a function
file:jquery-1.3.2.js
Line 4139

Looking into the error

this.options.easing is equal to a Boolean value of true when jQuery.easing[] is looking for a value of linear or swing.

Getting the exisiting code to run

If we change the example that rdworth posted to

$("#accordion").accordion({
    animated: "swing"
});

or

$("#accordion").accordion({
    animated: "linear"
});

it runs fine.

Possible Solution

If we still want to use a Boolean value the code around line 329-331 of ui.accordian.js [1.7.1] needs to be adjusted to something like this:

var animations = $.ui.accordion.animations,
duration = o.duration,
easing = (typeof o.animated === "boolean")?"linear":o.animated;

with this change animated can have the following values: "linear"

"swing"

true

This bug here: ​http://dev.jqueryui.com/ticket/4394 might be the real cause of this issue.
