System.MissingFieldException: Field not found

http://groups.google.com/groups?hl=...%26filter %3D0

The above thread is old but has anyone come up with a solution to this
issue? The intermittent problem started after I added a UserControl that
contains a third party control.

The problem does not occur on my development workstation. But I have a
development site on the same server which hosts the production site. I
simply copy the executable from this site to the production site. Invariably
when I access the production site again for the first time, I get a compile
error. If I replace the dll again, the site works fine. But only for another
few days until I get the same exception.

Obviously the temporary fix is unacceptable.Further to my previous post, here's the problem described in another forum:

http://gotdotnet.com/community/mess...141&Page=1&so=1

It appears this behavior occurs when a third party control is embedded in a
UserControl on non-development machines.

Anyone have any ideas? The application going down every few days is really
unacceptable. Thanks in advance.
