The is a good example for illustrating the difference in a DTML Method and a
DTML Document.

With the below code, when "objectItems('Folder')" is called in a DTML
Method, the list returned is a list of Folders in the DTML Method's
*container* object (often a Folder).  In this case, you'll get a list of the
Folders that are in the Folder where the DTML Method is.

When "objectItems('Folder')" is called in a DTML Document, the DTML Document
itself is the object where Folder items are being searched for.  Since there
cannot be Folder items in a DTML Document, you get an empty list.

When you call "PARENTS[-1].objectItems('Folder')", you're asking for the
Folder items in the root object (PARENTS[-1]), so you get a list of Folders
in the root Folder.

The only time you'll get a non-empty result is when you call
objectItems('Folder') from an object that can contain other Folders.  A
Folder object, of course, is the most common object that can contain

In short, the behavior you are experiencing is correct and by design.
