Only on Windows Mobile 7.5 (Mango), when changing the location of an IFRAME through Javascript. The x$.ready inside the framed page seem to fire too early, such that getElementById returns null all the time. Well, basically, the DOM isn't ready and we're trying to touch it.
The (dirty) workaround is in the reproducer: stick to the body tag's "onload"
Running the reproducer:
Save all the files. Add the IE-specific XUI javascript base.
Host the pages so they can be access through a mobile web-browser
Open iewrap.html on a Windows 7.5 phone.
Try the two buttons at the bottom.
