Marking this issue as Won't Fix, as there's no need to fix anything in ICEfaces. The javascript error occurs in the JSF code, and there's a way to avoid it.
The error occurs in the request() method in jsf.js, when the code goes through all the form elements, checking their 'name' attributes. The 'fieldset' element didn't get a 'name' attribute until HTML5, which doesn't seem to be well supported by IE11. So, IE11 throws an error because it cannot find a 'name' property on this empty 'fieldset' element that was added to the page.
The workaround is to give a 'name' property to the 'fieldset' element, in order to avoid this error on IE11. However, simply adding a 'name' attribute in the markup doesn't work, because 'name' doesn't seem to be a recognized attribute for 'fieldset' on IE11. So, the solution is to give this element a 'name' property via Javascript. The following code accomplishes this.
<fieldset id="fs1"></fieldset>
<script type="text/javascript">document.getElementById('fs1').name='';</script>
The value of the 'name' property can be the empty string. As long as there's a 'name' property on this object, the error won't occur.
