Hi! Is it possible to do a FetchSpecification over derived attributes? I tried and I got the error:
java.lang.IllegalStateException: sqlStringForAttribute: attempt to generate SQL for attribute 'attributeName' on entity 'EntityName' with undefined column name. You must define a column name for this attribute before attempting a database operation. Since the derived attribute doesn't have a real column it should work, no? :) Thank you in advance. Sincerely, Catarina
