I, like many others, have just put in the time to migrate my atlas ctp site over to ajax beta 1 only to find out that ajax extender controls no longer work with templated controls!! You've got to be kidding me! I just don't know how this could have slipped past testing, being that its such a major issue. I hate to rag on the dev team being that this is still a beta product, but this bug wasn't present in the last 2 ctp's and now is a major showstopper for me and many others...and unfortunately, the workaround that was posted by the team just won't do the trick for the majority of my controls. I'm now left with the lose lose decision of trying to stick it out and hack it together or going back to the July CTP :(
Please guys, get us an update soon!
