FetchSpecs over derived attributes

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
