I am trying to add a aggregated column to one of my entities and so this column should not get persisted or treated in any way by DevForce. I do this because I would like to show a column with all the invoices (seperated by a comma) in a table where the shipment info should be displayed (and this information should be possible to be edited) and the table should be generated automatically from the model (this works perfectly for entities).
I don't know if there is maybe some attribute that I could apply to my "table entity" so that I would only extend the base entity with these columns and the EntityManager knows that he has to treat this class like the base class or if I have to write some mapper code to create a base entity again and persist/work with this one.
