Please look at the following solution... I had implemented for similar scenario.

Because of that I am not able to develop a strategic solution.

Hope you understand my problem now.
Not really. You asked for a solution to a problem which was fetching data and
following relations. Note that your prefetches are not needed, they are only a

Nothing in Cayenne forces you to specify the specific entity in the generics. You can
treat the List as <PersistentObject> and handle it how you choose.
