Hi Martin,
Yes, I had that problem when I upgraded to SA 2.04.
For some reason I would say that the file in the JS error (WA ColumnTypes.js) is missing from your installation.
I could attach the JS to this thread, but I'm not sure that WA would be happy with me doing that.
Alternatively, there may well be another copy of this file on your hard drive that you could search for and copy to the location in the error. It's not an ideal way to resolve the issue, having to fish around files on your hard drive, but maybe Jason or Ray could open a support ticket for you if they see this thread anytime soon.
I have to say, apart from the "?" issue on the Update Behaviour DA 2.09 seems to have been working well for me alongside the other extensions.
Hope it gets sorted for you!
Cheers
Ian
