Mathew, A couple of things to know about the perl code: A CustomField object is handled by CustomFieldValue.pm and CustomFieldValue_Overlay.pm - when you make a new CustomField object in your perl code, the object gets attributes & methods from both of these files. If a method is defined in both files, the version in _Overlay is the one that's effective. Generally, the Overlay file is the one with the intersting stuff in it. The file names that are singular (e.g. CustomFieldValue.pm) represent a single object (row in the database) and are usually based on the generic RT::Record object. In your perl code you usually populate these objects by a Load method or as the result of a method call on another object. The file names that are plural (e.g. CustomFieldValues.pm) represent a collection of objects - in this case a collection of CustomFieldValue objects. They are usually based on the generic SearchBuilder object and are populated by a database query that returns multiple rows (e.g. by limiting and then iterating through the collection).
