I am trying to change versions of a table in a stand-alone script through the ArcPy ChangeVersion_management command. The table is an ArcSDE table, is registered as versioned and I can successfully create a table view of the table, which I then pass to the ChangeVersion_management command. This step of the script fails, with a:
'Parameters are not valid. ERROR 000840: The value is not a Feature Layer. Failed to execute (ChangeVersion).'
I talked to Support and they say that they added your customer ID to the bug and you should now see it through the customer care portal (http://customers.esri.com).
