I use the install_content_copy_import_from_file function to update content types, but I discoverd today that if you make some changes, the update doesn't happen.

For example, I changed a field from a textfield to a select list, and specified the allowed values. I rexported the cck type and tried to use install_content_copy_import_from_file to update it.

Unfortunately, I just got message like 'Field already exists, not updating' or something similar.

Is there a work-around for this behavior?
