I've got the paging and sorting covered in a component that abstracts Hibernate
Search's ability to handle all that.
My first crack at this problem was to use two more Seam components: the first
is an action component to interact with the user and the second to serve as
my ExtendedDataModel
As I keep studying Pete's seamdiscs code, I feel less confident about how much
I can really use beyond concepts. I understand the seamdiscs example is meant
to highlight the Seam CRUD application framework, but as a result I think a lot
of the data model integration doesn't apply to my case.
So I have done some research, and I have found that it actually isn't the
rich:datascroller I should be focusing on but rather the rich:dataTable to
which it is bound. It appears to me I need to do two things.
First, I need to write my own DataModel. It seems I am supposed to use the

@DataModel and @DataModelSelection
I prefer to handle all my pagination on the server with Hibernate, but I also

True enough. When combined with Seam, HS allows you to inject the
FullTextEntityManager directly.

basically what is found in the DVDStore example but with one catch. In that
