Please help me with this bug.
Can anyone tell me why this error appear in IE ?

Thanks!

Develop using Firefox with the Firebug addon installed..

The element does not exist.

Did you include /adapter/ext/ext-base.js (or any other adapter)?

[alyna]

i did all that, but nothing happens.
what does Ext.fly do. maybe i can explore myself this problem if i can understand the logic.
if u have some documentation on that it would help me very much.
thanx!

Hi,

i had this JS error on IE7 when using "Ext.form.ComboBox" and playing with CTRL + the mouse rolls.

To reproduce this error message, simply change the browser's zoom to 110% and select a ComboBox value.
When i come back to 100%, there is no more problem.

Yes, this is the problem (CTRL+mouse wheel) and still exists in 3.3.1, though a combo box wasn't visible, a tree was.

Wow, this is as obscure as it could get.
Does anyone in these forums know how this framework works ?

I don't mean to offend anyone but posting links to the useless documentation doesn't help at all. And yes i have firebug installed, which doesn't help either. Please don't post useless help like this, it's insulting, as if somehow reading that useless documentation and installing firebug has been sufficient for your superior brains. Pfft.

I'm getting this error as well and whatever everyone posted here means nothing to me. I don't have tab panels and even if my combo box caused this, I don't see anyone explaining why the error happens, what could cause it to happen and clues for where to look for issues.

"Ext.fly('elementId')" works great on typical HTML elements, but not so well on ExtJS form elements.
I fixed this issue by using "Ext.getCmp('elementId')" on my form elements, like combo boxes.
