>    Affects Versions: 1.4.10

> To reproduce:
> 1. Run provided quickstart project
> 2. Open in IE8. 
> 3. Upload a file. 
> Expected behaviour: 
> File is uploaded, and some basic information about uploaded file is displayed.
> Observed behaviour:
> IllegalStateException is thrown.
> The IllegalStateException is being thrown because the form is being submitted as a normal form. This is because the JS in handleMultipart that traverses up the DOM looking for the actual form is checking tagnames, and in IE8, the tagName of a <wicket:body> is body, so as soon as it hits a wicket:body, it returns false. I've provided a patch that checks for identity against document.body - an alternative is to check that the form.tagUrn is empty, as it would be for a normal HTML element.
