Rasmus Sööt commented on WICKET-1432:
-------------------------------------
Currently ajax doesn't work with IE if browser has High security settings and
Javascript is enabled. The problem is, that on High security settings ActiveX
is only enabled for trusted sites.
To reproduce:
In IE7 or IE8 select Tools->Internet Options -> Security tab-> Set security
level for Internet to High-> Click Custom level-> Scroll down to Scripting and
set Active scripting to Enable-> Click OK, Yes, OK-> Open URL
http://www.wicket-library.com/wicket-examples/ajax/editable-label -> Click on
multiple lines of textual content - Text box does not open and IE gives the
following error:
Message: Automation server can't create object
Line: 669
Char: 10
Code: 0
URI:
http://www.wicket-library.com/wicket-examples/ajax/resources/org.apache.wicket.ajax.WicketAjaxReference/wicket-ajax.js
Could somebody look into this? I'm not familiar with the codebase, maybe
something depends on having ActiveXObject for IE. Microsoft suggests using
XMLHttpRequest in IE7+ too, from
http://msdn.microsoft.com/en-us/library/ms535874%28VS.85%29.aspx -
To support versions of Internet Explorer prior to Internet Explorer 7, use the
following function to get the XMLHttpRequest object:
function getXMLHttpRequest()
{
if (window.XMLHttpRequest) {
return new window.XMLHttpRequest;
}
else {
try {
return new ActiveXObject("MSXML2.XMLHTTP.3.0");
}
catch(ex) {
return null;
}
}
}
> Detection of ajax transport type

> Environment: Windows Mobile + Opera Mobile 9.5 Beta
> Reporter: Sven Rienstra
> Assignee: Matej Knopp
> Priority: Minor

> Wicket currently detects wich type of ajax transport has to be used by
> detecting if the browser supports activeX. Wouldn't it be better to use
> activeX only if the browser is IE and lower than version 7, because as far as
> I know that's the only browser you would want to use activeX on.
> The reason i'm asking is because i'm testing with the new Opera Mobile
> browser (9.5 beta), ajax isn't working because wicket tries to use an activeX
> object. I fixed this for now in my own enviremont but maybe it's good to
> change this in a future release ?
