[EMAIL PROTECTED]: Re: [Wicket-user] debugging markup cannot be empty
look what you are doing here: final Panel3 p3 = new Panel3("Panel3",
url1);p3.setOutputMarkupId(true);add(p3);add(new Panel2("Panel2", url2){
public void updatePanel3(AjaxRequestTarget target){
Panel3 newPanel3 = new Panel3("Panel3",
url2);newPanel3.setOutputMarkupId(true);p3.replaceWith(newPanel3);on first
click p3.replacewith(newpanel3) works because p3 points to a component in a
page, but on subsequent clicks it doesnt because p3 is no longer in the page -
you replaced it - and you do not update the reference to it
what you should doreplace final Panel3 p3 local var with a field, then after
p3.replaceWith(newPanel3) add p3=newPanel3; so that p3 always points to the
right component-igor
