AjaxControlToolkit is undefined

I am pre-compiling this application using Web Deployment Projects, and so far everything runs fine EXCEPT that I get the following javascript error on the product pages:

This is the call that is causing the error

Sys.Application.add_init(function() {
    $create(AjaxControlToolkit.TabPanel, {"headerTab":$get("__tab_ctl00_ctl00_cph1_cph1_ctl00_ProductsTabs_pnlProductSpecs"),"ownerID":"ctl00_ctl00_cph1_cph1_ctl00_ProductsTabs"}, null, {"owner":"ctl00_ctl00_cph1_cph1_ctl00_ProductsTabs"}, $get("ctl00_ctl00_cph1_cph1_ctl00_ProductsTabs_pnlProductSpecs"));
});

Hello, did you get any responses to this?  DId you find the error?

I just started getting the same error on any Ajax page and nothing, as far as I know, has changed.

THanks, just checking.

No, nothing.  I've had to upload the source to the server.  I wish this could be addressed, because the performance is much better with pre-compilation
