Autocomplete: _resizeMenu raises exception in IE7

[james.a.rosen@…]

I am running the combobox autocomplete example (with a few changes to the way data is parsed) in IE7 and I get an exception in _resizeMenu. The problem is that the call to ul.width( "" ) is returning the element's width rather than the object itself for chaining. Thus, the subsequent call to width() raises an exception as numbers don't have that method.

I've tried to replicate this in a very limited manner but cannot. It _may_ have something to do with my CSS and/or a hasLayout issue. The only other information I can provide at this point is that when the call does succeed, the menu has an extremely large width -- as large as the window at least -- and thus goes partially off the screen to the right.

I am using jQuery 1.4.2 on IE7 with Developer Toolbar installed.

Attached is a screenshot of the debugger console. Notice that the watch expression (this.width("")) returns a long.

Closing as invalid unless you can provide a test case.

This branch of my fork of jQuery-UI fixes the issue, but it's more of a hack than a fix. I'd prefer to figure out why width( "" ) is returning the wrong thing.

I've tried again and failed to come up with a succinct example, but I have some more information.

When using jQuery 1.4.2 (which uses ("scrollTo" in elem && elem.document) to check whether the object is a window), I get the above broken behavior. Upgrading to jQuery 1.4.4, which defines jQuery.isWindow as (obj && typeof obj === "object" && "setInterval" in obj), the problem is fixed.
