I have found the problem to be in IE7's native XMLHttp support.
You'll notice that the getXMLHttpRequest function in Async.js tries to
first return the native XMLHttpRequest followed by the ActiveX
objects:
var tryThese = [
function () { return new XMLHttpRequest(); },
function () { return new
ActiveXObject('Msxml2.XMLHTTP'); },
function () { return new
ActiveXObject('Microsoft.XMLHTTP'); },
function () { return new ActiveXObject('Msxml2.XMLHTTP.
4.0'); },
function () {
throw new
MochiKit.Async.BrowserComplianceError("Browser does not support
XMLHttpRequest");
}
If IE7 native support is enabled (in tools --> properties -->
advanced), then the native request will be returned, and this native
request does not work for my purposes. If I force the activeX object
to be returned in IE7, I have no problems.
For now, I have reordered the functions in tryThese to start with
return new ActiveXObject('Microsoft.XMLHTTP'). I would rather that IE
fixed their native support so that I don't have to change anything in
Mochikit. Alternativly, you can uncheck the Enable XMLHttp support
box in IE7's advanced options.
I hope this helps!
