Multiple many to one relations in a database fail
This issue seems to be fixed in 1.5, but I'm unable to create multiple many-to-one relationships to the same collection.

Attribute with the requested key already exists. Attribute keys must be unique, try again with a different key.
TL;DR
Developers are facing issues creating multiple many-to-one relationships to the same collection in the database. A fix for this problem is suggested to be available in version 1.5.
