Yes, I removed the visibility related code and anything else for
simplicity and to focus on the actual problem.
What I actually want to achieve is something like:
public class MyPanel extends Panel {
Panel myAjaxLoadedPanel;
public MyPanel() {
add(new AbstractDefaultAjaxBehavior() {
@Override
protected void respond(AjaxRequestTarget target) {
String someParameter =
RequestCycle.get().getRequest().getParameter("someParameter");
if(someParameter.equals("1") {
myAjaxLoadedPanel = new Foo1Panel("myAjaxLoadedPanel");
}
...
else {
myAjaxLoadedPanel = new FooXPanel("myAjaxLoadedPanel");
}
target.addComponent(myAjaxLoadedPanel);
}
}
myAjaxLoadedPanel = new MyDefaultPanel("myAjaxLoadedPanel");
myAjaxLoadedPanel.setOutputMarkupId(true);
add(myAjaxLoadedPanel);
}
