Hello!

I just encountered a very strange error which only occur in Internet Explorer 8 and only when doing certain postbacks in a special order.

The following javascript error occurs: 'theForm.__EVENTTARGET' is null or not an object.

When disabling PIE, the issue disappears. It is also somehow messing with the postbacks. I have one postback which switches the viewstate so some other content can be displayed, but with PIE enabled it won't.

Any suggestion how to tackle this? I wouldn't mind a quick and dirty solution. I'd rather solve it q&d than rebuild the whole site with images as rounded corners etc etc....

If you want to try it out yourself, or someone in the PIE-team want to see the bug in action, PM me and I'll send you a link.

EDIT
The PM function seems to be inactive, just post here if you want a link and we'll just figure out way...

jason, you have any clue how this happens? Anything is appreciated, really need to solve this!

I'm really unfamiliar with how ASP.NET works internally so unfortunately I'm not much help. PIE itself would not be removing expandos like theForm.__EVENTTARGET, so the best I can guess is that the .NET code is maybe doing some sort of DOM traversal relying on only elements it knows about to be present, and getting off track when PIE's inserted elements are present...?

Feel free to email me a link and I'll try to take a look, but like I say I really don't know what .NET does behind the scenes so I'm not too optimistic I'll be able to help.
