function outerWidth doesn't work

[jquery@…]

In version 1.8.0 $('li#id').outerWidth() returns DOM object instead of integer.

Well it doesn't work with jquery-ui-1.8.20/ui/minified/jquery.ui.core.min.js but it works with jquery-ui-1.8.22/ui/minified/jquery.ui.core.min.js.

Please upgrade jqueryUI to 1.8.22, as that's the one that's compatible with jQuery 1.8

From my analysis

In 1.7.2, any truthy value passed to outerWidth would be considered include margin true.

In 1.8.0, only true boolean is considered include margin true

That's because in 1.8, the dimension functions are now setters too, and not just getters! You can do

$(elem).outerWidth(50);

And automatically set content+padding+border to 50! Or you can do:

$(elem).outerWidth(50, true);

And automatically set content+padding+border+margin to 50! Awesome, right?

Needs docs.

yes, that's awesome but VERY DANGEROUS change! a lot of code uses outerWidth() as getter. Now, everything's broken. Everybody needs a search-replace their code if they want to upgrade to 1.8.0. It's not a safe change for javascript code which has no compiler to make this change revealed.

No problems. outerWidth() continues to work as a getter. Before, it accepted either no arguments or a single Boolean argument. If you were passing it something else, you were doing it wrong, which is VERY DANGEROUS because it could break when the API is updated.
