Lonnie Fulton commented on WICKET-1646:
---------------------------------------
This is what i currently do. I followed microsofts documentation on how to
fallback to using a ActiveX object if native XMLHTTP is disabled
(http://msdn.microsoft.com/en-us/library/ms537505(VS.85).aspx) and simply added
the following to wicket-ajax.js. You just need to make sure this snippet is
inserted before Wicket.Ajax = { ... is called.
/**
* Check to see if the native XMLHttpRequest has been disabled for IE7,
* if so fallback to using the ActiveXObject.
*/
if (Wicket.Browser.isIE7() && !window.XMLHttpRequest) {
window.XMLHttpRequest = function() {
try {
return new ActiveXObject('MSXML2.XMLHTTP.3.0');
}
catch (ex) {
return null;
}
}
}
I have been using this for awhile on our production server and have had no
problems. I hope this can be incorporated into 1.3.4.

> Key: WICKET-1646
> URL: https://issues.apache.org/jira/browse/WICKET-1646
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.3.4
> Environment: OS: Windows XP SP2
> ServletContainer: Jetty 6.1.6
> Browser: IE 7
> Reporter: Jarmar Fowler
> Assignee: Matej Knopp
> Fix For: 1.3.4

>
> AjaxFormComponentUpdatingBehavior works with Firefox, but doesn't work when
> using IE7.
> I also observed similar problems when using AjaxEventBehavior as well.
> The error returned via the ajax debug console was: "Could not locate ajax
> transport. Your browser does not support the required XMLHttpRequest object
> or wicket could not gain access to it".
> Below is a simple example that should demonstrate the problem.
> Example.java
