Copying Items Between Databases Doesn't Bring Custom Attributes Properly

[TimP]

Sigh.

I've never actually seen the feature function as expected. I just now did it again, and it fails exactly as I describe.

I drag a new template I've created, based on the document template with new attributes and a custom form that includes those attributes. The template item in the target database is missing some (not all) of the new attributes and the form is different because of the missing attributes.

So, I've attached a tiny version of the source database that I've been using. If any of you can drag the template item "Research Document", in tact, with all attributes and the form, into a new empty database, I'll have to be surprised.
