ADF Rich Client Demo does not work in MSIE 7.0 with Native XHR disabled

http://jdevadf.oracle.com/adf-richclient-demo/faces/index.jspx
Is this suposed to work in MSIE 7.0 ? I hope so but not with
Native HMLHttp request disabled in MSIE configuration ;-)



AdfXMLRequest.superclass.Init.call(this);
this.isSynchronous=false;
this.callback=null;
this._state=AdfXMLRequest.UNINITIALIZED;
this.headers= new Object();
this.xmlhttp= new XMLHttpRequest();}


Any docs on this please ?
