Part Parameter Error Fixed in Civil 3D 2012

For anyone who has made any custom changes to optional parts within a pipe catalog, the following is a familiar scene.

Autodesk recently released Civil 3D 2012 Update 2.  While looking through the list of issues that were resolved with this update, I came across the following:

In the past, this error occurred because the parameter wasn't configured properly, or most likely because the template containing the custom parameter was set in options to be QNEW.  In the past, I always told my clients that this was a benign error, and to simply hit OK.  Now with the update, the error is a thing of the past.  On a side note, you can not run an automatic removal of this update.  You will need to uninstall Civil 3D 2012 and re-install it.
