Whenever I try to duplicate a (user created) list, I get the following error message:
Could not duplicate list: Duplicate entry 'cws_list_variantType' for key 'u_code' 
The list in this example did not have any children (yet).
'cws_list_variantType' is the "List code" I gave to the newly created list.
Seems like the duplicate function doesn't generate a non-colliding "list code".
Am I using it wrong?
Thank you very much in advance.
