correct..

yes.. correct.
> But, how would the toolbar get the data to display?
public class TotalCounter extends AbstractToolbar
{
public TotalCounter(final DataTable dataTable)
{
IModel<Integer> model=new LoadabledDetachedModel<Integer>()
{
public Integer load()
{
return dataTable.size()
}
}
WebMarkupContainer span = new WebMarkupContainer("span");
add(span);
span.add(new AttributeModifier("colspan", true, new Model<String>(
String.valueOf(table.getColumns().length))));
span.add(new Label("count",model));
}
> What would the html markup for this toolbar be like?
<wicket:panel>
<tr class="navigation">
<td wicket:id="span">
<span wicket:id="counter"></counter>
</td>
</tr>
</wicket:panel>
