Anna,
Third parameter ( "Example DownloadLink" in your case) is just an
alternative fine name: see onClick() method to see how it is used. Can
you try following panel?
import java.io.File;
import org.apache.wicket.markup.html.basic.Label;
import org.apache.wicket.markup.html.link.DownloadLink;
import org.apache.wicket.markup.html.panel.Panel;
public class DownLoadLinkPanel extends Panel {
private static final long serialVersionUID = 1L;
/**
* @param id
*/
public DownLoadLinkPanel(String id) {
super(id);
DownloadLink dl = new DownloadLink( "download", new File(
"wat-application/images/addmore.jpg" ), "AddMore.jpg" );
add(dl);
dl.add(new Label("text", "Example DownloadLink"));
}
}
----
DownLoadLinkPanel.html
<wicket:panel>
<a wicket:id="download"><span wicket:id="text"></span></a>
</wicket:panel>
-------------------
and then
return new DownLoadLinkPanel(componentId);
