I've got a page that uses CalanderExtenders, MaskedInput, AlwaysVisible controls, and collapsable panels, probably a few other things. All in all, it's a fairly rich UI. I recently started noticing in IE (but not FireFox) that when I load one of the pages, there is a message "Error on Page" in the bottom left corner of IE. Expanding this error tells me:
Line: 1
Char: 1
Error: Object required
Code: 0
So I would like to fix this error. When I look at the source of my page (as I am assuming this is a client side Javascript error), there is nothing on line 1 except a space. And the next several lines don't have anything to do with Javascript either.
The strangest thing is that everything on the page seems to work fine. But I can't have this random error showing up when our app goes into production. Can anyone give me a little guidence on how to go about troubleshooting this, asside from simply going through my page and ripping out all the AJAX controls till I find it???
