[Building Sakai] GenericDAO and composite-id

[Aaron Zeckoski]

I have not really tried this but it should be able to accept any normal id.
It looks like the hibernate lookup by id is failing though so the
short answer might be no.
I can probably add in an additional lookup attempt but it would
require an update.
