[Wicket-user] Ajax Stuff in Wicket 1.2

[Ayodeji Aladejebi]

What may be wrong with these code

 

public class MyAjaxPage extends WebPage {

private int count = 0;

public MyAjaxPage(){

 add(counter = new Label("counter", String.valueOf(count)));

 

 add(new AjaxLink("ajlink") {
            public void onClick(AjaxRequestTarget target) {
                // Increment count
                count++;
                RequestCycle rc = getRequestCycle();
                rc.setRequestTarget(new ComponentRequestTarget(counter));
                target.respond(rc);
              
            }
           
        });
}

 

Anyway, it did not even initialize cuz, tomcat returned

 

java.lang.NoSuchMethodError: wicket.ajax.markup.html.AjaxLink.add(Lwicket/behavior/IBehavior;)Lwicket/Component;
wicket.ajax.markup.html.AjaxLink.<init>(AjaxLink.java:52)
