Unable to cast object of type System.String to type System.Collections.ArrayList.

When editing products you get an error message "Unable to cast object of type 'System.String' to type 'System.Collections.ArrayList'."

The issue was caused by a caching name conflict.

There are several solutions.

1. Turn caching off while working in the admin section and then turn it back on when you are finished.
2. Limit the editing of products to either Products -> Product Manager or Products -> Edit Products (don't use both).
3. Upgrade to or higher where the issue has already been resolved.
