IE9 and Infragistics ASP.NET 2009.2 __defineGetter__
posted

UPDATE: we're using 2009 2 IG package, for example (web.config snippet): Infragistics35.WebUI.UltraWebGrid.v9.2, Version=9.2.20092.2137

We've started testing our application with IE9 (RC). It seems that there's a JavaScript error rising from IG's components:

As you can see, the problem is from the following code:

if (document.implementation && document.implementation.createDocument)
{
    igtbl_XSLTProcessor.prototype.__defineGetter__("output", function _igtbl_XSLTProcOutput()
    {
<snip>

When switching to compatibility view (IE7/8), it works ok.

After debugging a little, it seems like the code "document.implementation.createDocument" (see above) was probably meant to filter out IE and to run on mozilla only. However, in IE9 'createDocument' isn't 'undefined', and the next line of code breaks, as "__defineGetter__" is mozilla-only and isn't supported in IE browsers.

Naturally, I'd hate to tell our customers that our recently released web application breaks on the latest IE browser and that they'll have to use Compatibility View.

Please advise A.S.A.P.
