Inactive fields are not included in lists of available fields until their modules are enabled

If you are using Imagefield and Date modules, there are a few considerations to factor in (as of Dec 20, 2008):

Imagefield

- Enable CCK and run update.php. Do NOT enable Imagefield at the same time.
- Download the latest Imagefield dev module 6.x-3.x-dev (2008-Dec-15) and patch it.
- Then, enable Imagefield and run update.php again.

- Otherwise, you get an error [imagefieldname] is an inactive Image field that uses a Image widget.

Date

- Enable CCK and Date, Date API, Date Popup, Date Timezone ALL at the same time (whether you use Popup or not) and run update.php.
- Disable Date, Date API, Date Popup, Date Timezone. Uninstall them. Re-enable them and run update.php again.

- Otherwise, you get an error [datefieldname] is an inactive Date field that uses a Select List widget.
- (Optional: you may now disable Date Popup if you don't use it.)
