Hi, shouldn't the provider implement a method count() which gives the total number of records?

Hello everyone,

So I feel there is something I am overlooking in all my work on this. I have a Wicket 1.4/Spring2.5.6/hibernate 3.2/ app that I cannot get quite
right.  I have a SortableDataProvider that I am trying to populate by:

public class ABCTablePanel extends Panel {

 public ABCTablePanel (String id) {
   super(id);
   ABCProvider abcProvider = new ABCProvider();
DefaultDataTable table = new DefaultDataTable("abctable", getColumns(),
abcProvider , 10);

   add(table);
 }

private List&lt;IColumn&lt;Abc&gt;> getColumns() {
     List&lt;IColumn&lt;Abc&gt;> result = new
ArrayList&lt;IColumn&lt;Abc&gt;>();
     result.add( new PropertyColumn(new Model("Abc Description"),
"AbcDescription",
"AbcDescription" ));
result.add( new DatePropertyColumn(new Model("Abc Date"), AbcDate",
"AbcDate" ));
...
}

}


Then my provider:
public class AbcProvider extends SortableDataProvider {

private List list = new ArrayList( );
   private SortableDataProviderComparator comparator = new
SortableDataProviderComparator( );
   @SpringBean
   private AbcManager abcManager = null;

   public AbcProvider( ) {
       // The default sorting
       setSort( "abc.abcDescription", true );
   }

    public void refresh( List list ) {
       list.clear( );
       list.addAll( abcManager.getAllGaps( ) );
   }

   @Override
   public Iterator iterator( int first, int count ) {
getAllAbcs( ); // method that calls a manager, calling hibernate,
and populates "list"
       List newList = new ArrayList( list );

       // Sort the data
       Collections.sort( newList, comparator );

// Return the data for the current page - this can be determined
only after sorting
       return newList.subList( first, first + count ).iterator( );

   }
   @Override
   public IModel model( final Abc object ) {
       return new AbstractReadOnlyModel( ) {
           @Override
           public AbcgetObject( ) {
               return (Abc) object;
           }
       };
   }


When I run this all appears well, except the call is never made to populate the table. I just get "No Records Found" beneath my column names, and the
debug points are never hit when I refresh or load the page.

Thank you in advance for any help you can offer.
