> When loading hybrid cube definitions via REST API, there is no check for duplicate cube names is the list. If due to a user error or incorrectly generated list of cubes by an external application/script the same cube name is listed more than once, new or updated hybrid cube will contain the same cube listed multiple times.
> It does not seem to cause any immediate issues with querying, but it's just not right. REST API should throw and exception, when the same cube name is listed multiple times.
