Google was not as usefull as usual and i can't find solution to this error. I'm using Seam 2.0.1.GA and jboss-4.2.2.GA project was generated with seam-gen.
When I change component to rich:dataTable it works great.

Don't know what the problem could be, but in which scope is the bean backing the table?

And do you get that exception whenever it fetches more data for the table or only when you scroll to the very end of it?

@Scope(ScopeType.APPLICATION)
@Name("dataTableScrollerBean")
public class DataTableScrollerBean implements DataTableScroller{

But it should work with Seam bean also (this is example code from richfaces). This is not a problem with lifecycle of bean because bean is working correctly (I use:
private ArrayList<DemoInventoryItem> selectedCars
and it just works - I mean it shows selected columns)...

I get that exception whenever it fetches more data for the table.

Hmm, strange.

I use the scrollableDataTable with beans in session scope or long running conversations without problems.

My working case is using Seam beans and I get the data from the backing bean (no outjection) without any issues.

Does it work when using a normal data table paired with a datascroller?

Yes, it works with datascroller.

You better move this question to the RichFaces forum.

You will find the link here http://labs.jboss.org/jbossrichfaces

Good luck

Thank You for Your help so far, but can You publish Your working code with scrollableDataTable? This is very interesting component and I want to use it in my new Seam application. I can rebuild my project to work with this component.

The page and class are quite big, so I'll post some snippets.

Backing bean, there is a fetch data action which populates the rtCache list.

@Name("runningTasks")
@Scope(ScopeType.SESSION)
public class RunningTasksBacking {

    private RunningTasksDAO runningTasksDao;
    List<RunningTask> rtCache=null;

    public List<RunningTask> getRunningTasks(){
        return rtCache;
    }

XHTML:

<h:form id="runningTasksForm">
<rich:scrollableDataTable
          id="taskTableScrollable"
          rowKeyVar="rkv"
          frozenColCount="1"
          height="400px"
          width="650px"
          onRowMouseOver="this.style.backgroundColor='#F1F1F1'"
          onRowMouseOut="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'"
          value="#{runningTasks.runningTasks}"
          rendered="#{not empty runningTasks.runningTasks}"
          rows="50"
          sortMode="single"
          var="task">

     <ui:include src="/jsf/admin/rtv/tableCols.xhtml"/>
</rich:scrollableDataTable>
</h:form>

The tableCols.xhtml contains normal rich:column stuff, broke that out into a separate file because the same data can be seen in a normal data table as well.

Hope this helps a bit.
