I wanted to move (or say copy, since there is no way to 'move' a document type node) that currently existed under a master document type.

I created a new document type which would be my master. I then right clicked on a current document type, selected copy, and then pointed to the newly created document type 'master'.

I get the following error:

Cannot insert duplicate key row in object 'dbo.cmsPropertyType' with unique index 'IX_cmsPropertyTypeUniqueID'. The duplicate key value is (f9a05dc0-d239-461f-81b3-b0db9545c98d). The statement has been terminated.

Is there a problem with copying document types in v7?
