Problem with Table Filter!

Hi..

I have a problem implementing the Table filter, I develop a Web Dynpro that shows in the table information from R/3, using the Bapi_Flight_Getlist.

In the method Sort work ok, but the problem is whit the Filter funtion.

I follow this tutorial, but whit some changes for to filter the table that get information from the Bapi_Flight_Getlist,

[https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/f024364b-3086-2b10-b2be-c0ed7d33fe65]

But I get the following Error when I try to filter:

com.sap.tc.webdynpro.progmodel.context.ContextException: DataNodeInfo(MyTableApp.Source.Output.Flight_List): value node is created without a reference

I have the following nodes:

Source = all data node

TableSet = Filter Values

FilterAtributes=Filter Atributes

 public static void wdDoModifyView(IPrivateMyTableAppView wdThis, IPrivateMyTableAppView.IContextNode wdContext, com.sap.tc.webdynpro.progmodel.api.IWDView view, boolean firstTime)
  {
    //@@begin wdDoModifyView
	if (firstTime) { 
	  IWDTable table = (IWDTable)view.getElement("Table_0"); 
	  wdContext.currentContextElement().setTableSorter( new      
		  TableSorter(table, wdThis.wdGetSortAction(), null)); 
		  
	wdContext.currentContextElement().setTableFilter( 
			  new TableFilter( table, wdThis.wdGetFilterAction(),  
								(IWDNode)wdContext.nodeSource().nodeOutput().nodeFlight_List(), null ) );
