Validate the Repository Model

At this point, if you have followed all the steps in the tutorial so far, there should be no validation errors.

If you omitted to perform any of the steps, it may result in a validation error. For instance, if you create a relationship attribute group but leave it empty (without adding any relationship attributes). Or if you fail to connect a relationship attribute group to a relationship. Or if you forget to provide a reverse relationship name for a relationship.

Check the Problems tab for any errors.
