CRM 2011 - "An error has occurred." when opening a record

Haven't blogged in a while, but thought that since I ran into an issue today that I would share my experience and resolution to the problem. One of our clients said that when they opened a form to validate data, they received this error:

After running a trace on the CRM server, all I could find in the log was an "object reference not set to an instance of an object" error (which doesn't help all that much). So, after doing some more digging, I found this article:

Apparently, the problem has to do with a recently added field which got "stuck" (for lack of a better term) during your last publish of customizations. To resolve the problem, you need to remove the field (in my case, I didn't know which field was causing the issue so I had to remove sections until I found it. A pain, I know, but it's better than having to recreate the entire form.), publish and re-add the field to the form. Once you publish again, try opening the record. The problem should be fixed.

Hope this helps you as much as it helped me!
