Today while working on an SP1 MOSS installation our content editor web part started raising an error on key down. The only difference that we could determine is that this build was part of a slipstream installation of MOSS rather than RTM, then WSS SP1 and MOSS SP1. It appears that the JavaScript files BFORM.JS and FORM.JS did not get updated by the service pack.


Internet Explorer Script Error
An error has occurred in the script on this page.
Line: 3032
Char: 2
Error: Object expected
Code: 0
URL: http://server/_layouts/RTE2PUEditor.aspx

After hours of searching I found this post: So I am re-posting in hopes that it will make finding the info easier for others.

The solution is to copy the JS files from a working SP1 server and copy them into \layouts\1033 and then start worrying about what else failed to update.
