I want to be able to get the data for the selected row in a scrollabeldatatable. I would like to use the "selection" attribute of the scrollabledatatable. Seems simple enough. here is my view code for the scrollabeldatatable tag:

<h:form
 id="casetableform"
 style="width:802px;margin:auto;border:solid 1px">
<rich:scrollableDataTable
 id="casetable"
 rows="50"
 columnClasses="col"
 value="#{caseList}"
 var="case"
 sortMode="single"
 width="800px"
 height="600px"
 selection="#{CASELISTFORM.rowSelected}"
 binding="#{CASELISTFORM.tbl}">
.
.
.

here is my backing bean:

@Stateless
@Name("CASELISTFORM")
public class CaseListFormBean implements ICaseListForm {

 private Selection rowSelected;
 private UIScrollableDataTable tbl;
.
.
.
public Selection getRowSelected() {
 return rowSelected;
 }

 public void setRowSelected(Selection rowSelected) {
 this.rowSelected = rowSelected;
 }

 public UIScrollableDataTable getTbl() {
 return tbl;
 }

 public void setTbl(UIScrollableDataTable tbl) {
 this.tbl = tbl;
 }

The error I get using the type for the binding UIScrollabelDataTable is :

SEVERE: Error Rendering View[/caselist.xhtml]
javax.faces.FacesException: javax.el.ELException: /caselist.xhtml @213,33 binding="#{CASELISTFORM.tbl}": java.lang.IllegalArgumentException: argument type mismatch

OK - so I tried HtmlScrollableDataTable as the type instead. It gives me an exception stating that "casetableform:casetable is not of type UIScrollabelDataTable" - that is why I switched types. Yet neither binding works.
The error occurs when the scrollableDataTable is rendering - I want to be able to call a serverside method from a richMenuItem that gets the selected row, then delete the row and have the grid remove the row without rerendering the whole grid (the last part may be a separate question but any help is appreciated)
