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 do
replace 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

So wrote a smaller sample program and I see the same issue - here is the

missing.
