isField is null in IE 8

[jlee@legatoppm.com]

Works fine on FF, Chrome, however, on IE 8 with extjs 4.1.1a I'm getting this exception in the extjs library.
Any suggestion or workaround on this?

Can you post some code to reproduce this ? When does this happen while using our components ?

You need to start using an IDE with syntax checking:

fields: [
        {
        	name: "Resizable",
        	type: "boolean"
        },
        {
        	name: "Draggable",
        	type: "boolean"
        },        
    ]

IE doesn't like invalid syntax, with trailing commas...

Thanks for the quick response.

I got that class from this sample
