Ah, now I see, you are right.
It looks like it isnt a business logic interface as it is so easy to
implement with plain sql, but as soon as you have a complicated business
logic and would like to paginate you have to tell this logic to do so.
However if DataPage or an equivalent was part of a non-ui library like
commons-collections then this might be acceptable.
So we should ask them to do so. Myfaces already use commons-collections,
so this wouldnt introduce a new dependency.
