I have a portal page in my application running various portal panels using grids. I have moved my code to Ext 3.0 RC 1 and all of my portal panels using grids are working fine. I added a chart from the chart examples into a portal component and everything is good as far as adding/viewing/moving but when I try to close the chart portal component I am getting a
Code:
Line: 1
Error: 'null' is null or not an object
I am running IE 8, FF3 is working fine. The IE 8 debugger leads me to this:

Code:

}
