I'm trying to create a relationship class with Python using a GlobalID.

When I use Python it gives me the error:

Failed to execute. Parameters are not valid. ERROR 000800: The value is not a member of GLOBALID. Failed to execute (CreateRelationshipClass).

When I try to use the Create Relationship Class tool through the Toolbox, I get the same error. If I select GlobalID as the primary key, it will ONLY let me select a GlobalID as the foreign key. It will not let me select a GUID of my choice.

But when I'm in ArcCatalog and right click the Dataset and go to New > Relationship Class...

It works!

What's wrong here?
