After the timer has fired, AbstractAjaxTimerBehavior automatically
registers another timeout for the form inside PanelOne.
But at that point PanelOne is no longer in the component tree, it's
replaced by PanelTwo already.
I'd recommend adding the behavor to the container instead:
final WebMarkupContainer wmc = new WebMarkupContainer("container");
wmc.add(new AbstractAjaxTimerBehavior(Duration.seconds(5)) {
@Override
protected void onTimer(AjaxRequestTarget target) {
PanelTwo two = new PanelTwo("panel");
wmc.addOrReplace(two);
target.add(wmc);
stop(target);
}
});
add(wmc);
wmc.add(new PanelOne("panel"));
This way you won't have to pass 'wmc' to PanelOne any longer.

The problem is that this leads to a Page not found error. The problem
is that the Panel which should be replaced is still looked up in the
findPage() method. But findPage() returns null on that component, so
this error is thrown.

Hi,
i created a small wicket application to show my problem:
https://github.com/olze/WicketPanelReplace
The first panel gets displayed, after a few seconds it should be
replaced by the second panel. Is there any way to achieve this
behavior with that kind of architecture?
If not, how should a ajax based panel wizard work? Any recommendations?
Thanks in advance.
