Hi,

When I open a page with the rich:scrollableDataTable I get a following exception:

Cannot convert org.richfaces.model.selection.SimpleSelection@1f of type class org.richfaces.model.selection.SimpleSelection to interface org.richfaces.model.selection.Selection

The rich:scrollableDataTable looks like this:

<rich:scrollableDataTable reRender="field" rowKeyVar="row" height="200px"

 width="200px" id="userListId" rows="5"

 value="#{trip.members}" var="member" sortMode="single"

 selection="#{manager.selectedMember}" >

 <rich:column>
 <h:outputText value="#{member.first} #{member.last}" />
 </rich:column>

 </rich:scrollableDataTable>

The manager bean:

@Stateful
@Name("manager")
public class ManagerBean implements ManagerLocal {


 @PersistenceContext(unitName = "ds")
 private EntityManager em;
 @In(required = true)
 private Trip trip;
 private SimpleSelection selectedMember = new SimpleSelection();



 public SimpleSelection getSelectedMember {

 return selectedMember;
 }

 public void setSelectedMember(SimpleSelection selectedMember) {


 this.selectedMember = selectedMember;
 }

 @Destroy
 @Remove
 public void end() {

 }


}

I look forward to any help. Thank you in advance.
