View Full Version : 'Ext.fly(...)' is null or not an object error in IE8 using DataView

31 Oct 2011, 1:01 AM

I am using Ext 3.3.1 and i have noticed one problem while using DataView. When i am using "overClass" config option of DataView, i have witnessed 'Ext.fly(...)' is null or not an object error in IE 8, when i try to add lots of data items in quick succession.

I tried to debug this issue and found out that it is related to onMouseOver method in DataView (which is internally calling EventManger's getTarget method).

Can anyone please help me how to fix this problem ?
