[jboss-user] [JBoss Seam] - Trinidad table binding

I'm writing an application using a mix of Trinidad and RichFaces controls. I used the SeamDisc example in CVS for the setup and it's working. 

I'm using a tr:table with the following header:
					<tr:table id="partyTypeList" value="#{partyTypes.dataModel}"
  | 						var="partyType" rowBandingInterval="1" rows="10"
  | 						rowSelection="multiple" binding="#{partyTypesManager.table}">

The binding does not work, I get a
javax.el.ELException: /party/partyTypes.xhtml @31,68 binding="#{partyTypesManager.table}": java.lang.IllegalArgumentException: argument type mismatch.

As you can imagine I carefully used the example in the TRinidad web site and double.checked the code of the bean, that is:

  | @Scope(ScopeType.SESSION)
  | public class PartyTypesManager {
  | 	public void performDelete(ActionEvent action){
  | 		UIXTable table = getTable();
  | 		Iterator selection = table.getSelectedRowKeys().iterator();
  | 		Object oldKey = table.getRowKey();
  | 		while(selection.hasNext()){
  | 			Object rowKey = selection.next();
  | 			table.setRowKey(rowKey);
  | 			PartyType pt = (PartyType) table.getRowData();
  | 			System.out.println("PartyType "+pt.getId()+" marked for deletion");
  | 		}
  | 		table.setRowKey(oldKey);
  | 	}
  | 	private UIXTable _table;
  | 	public UIXTable getTable() {
  | 		return _table;
  | 	}
  | 	public void setTable(UIXTable table) {
  | 		this._table = table;
  | 	}
  | }

I red an old post that said to not try to use a binding of a trinidad table in Seam. Is it still true? The SeamDisc example did not bind any table to a backing bean, so i do not have any hint. 

The binding is necessary to use the multirow selection feature, one of the many differences between the Trinidad table and the RichFaces table.
