Extender Controls May Not Be Registered Before Prerender
Chances are if you see this one you are missing a call to Base.OnPreRender(e) in the overide of the OnPreRender event. Adding the function call there will fix the problem. Apparently this wasn’t an issue in the first release of ajax, when I recieved it, it was after upgrading a perfectly fine app to the newest version of Ajax.
