TabbedPanel tb=new TabbedPanel("tb");
tb.setOutputMarkupId(true);
<div wicket:id="tb"></div>
on panel 2...
add(new AjaxFallbackLink("switch"){
public void onClick(AjaxRequestTarget target) {
TabbedPanel tb = findParent(TabbedPanel.class);
tb.setSelectedTab(0);
if (target != null){target.addComponent(tb);}
}
});
this is how the framework is meant to be used. the following works
with ajax when js is enabled and a regular refresh when js is
disabled.
clean and simple.
