if you put a wicket:id on the [a name="setup"] and make it a
webmarkupcontainer you can return from link.getanchor()
anyways, im just looking at the source the same as you and i see a
couple of other ways to do it. eg you can override geturl() and append
the anchor there yourself. i recommend attaching wicket sources to
your ide.

i dont know what the exact javascript is, but you can output it in
renderhead(iheaderresponse r) { if (!form.isvalid()) {
r.renderonloadjavascript("gotohash");}}
