How to tell (on the server) which row of an extended data ta

[dxxvi]

With a rich data table, I can write something like this

<rich:dataTable value="#{bean.cars}" var="car">
 <a4j:support event="onRowClick" reRender="...">
 <f:setPropertyActionListener value="#{car}" target="#{bean.selectedCar}" />
 </a4j:support>
 <rich:column ....
</rich:dataTable>

This doesn't work for an extended data table.

I've just read the developer guide and found out that the selection attribute of the extended data table can help me. The developer guide reads "In the example `selection' attribute contains object with selected rows". What Java type of the object that I specify in the `selection' attribute?

Until now, whenever I want to display a list of object using rich data table (or extended data table), I give that data table a list of object. I don't build any particular data model. I wonder if it's the correct way to use RichFaces data tables.

I found the solution at http://www.jboss.org/community/docs/DOC-11857 and the DataTableScrollerBean source code (in the demo).
