Hello,

I am testing my gwt-ext app in browsers, it doesn't show warning in Chrome and in FF but in the status bar of IE (6, 7, and 8), I always have this "Done, but with errors on page" warning. But i cannot find anything wrong with the behavior of the application, it still works fine. when i look at the error message detail, this is what it's saying:


Webpage error details

Message: 'Ext' is undefined
Line: 9
Char: 1
Code: 0
URI: http://xxx.xxx.org:8050/ipres/ipres/js/columntree/ColumnNodeUI.js



can i just supress this warning through my application (I wouldn't want to freak out my users when they see this) or is there something i need to fix with the specified js that shouldn't bring any changes in the application. I'm not sure I want to touch ColumnNodeUI.js since I didn't make any prior changes to it, I just imported the gwt-ext in my app and used it. nothing more.

I would really appreciate your help. Thanks!

Regards,

Chris
