Yes it is not possible to create an association at the moment between classes that are not mapped to a table in the designer. However this will not be the case in the next internal build or service pack as this functionality is part of our plans but, unfortunately we were not able to deliver it for this version. There is a workaround at the moment and you have to accomplish the following steps in order to achieve you goal:
- Perform "Update From Database" in order to import the tables that the "Update Database from Model" wizard has created.
- Associate each class with its corresponding table. You can accomplish this in the "Mapping Details Editor".
You can find more information regarding the "Mapping Details Editor" in our documentation under: OpenAccess ORM Visual Designer > OpenAccess Model Tools > Visual Designer > Mapping Details Editor.
I hope this helps you to accomplish your goal .Please have in mind that this is just a temporary workaround which will not be necessary in our future service pack or internal build versions.
