I didn't know SP1 beta would break the pre-release code we have?
SP1 beta is a bit of a pain to install. I have it on one machine (laptop) for testing, but on our production machines, I don't want to install it, as it might break something. I was under the impression that the dynamic data code in sp1 beta was the latest?
Or is that older code? If not sure, please get the latest preview build from the codeplex site for dynamic data, that's the latest build they have made public (and likely newer than the sp1 code)
