T5: Grid component with SQL-based paging/sorting
Hello,
I'm a newbie, trying to learn T5.
I have a grid component, but I don't want Tapestry to do the work of
sorting/paging data in the grid component; I'd like to push that off to
the database. (The source of the data is a database accessed via
Hibernate). How can I do this? I know that in T4, I could write a DAO
class that implemented IBasicTableModel, and in that DAO class, I could
put the logic to include the order by/paging in the query. But I can't
find anything similar to that in T5. Please help?
Thanks,
Andy

It's interface GridDataSource.
What you may be missing is that Tapestry convieniently coerces
java.util.List to GridDataSource for you. However if you connect the source
parameter of the Grid component to an actual GridDataSource, you can have
fine control over sorting and otherwise efficiently providing data to the
Grid.
