>link has overridable String getAnchor()
It's actually 'Component getAnchor()' and I don't understand where to get
this anchor component. There is little javadoc in getAnchor() but
setAnchor(Component c) has more details but I don't understand it at all.
My page is like this:
=== top of page ===
...
<a href="#setup">Go To Setup</a>
... very long stuffs follow
.
.
.
bottom of page
<a name="setup">Setup Form</a>
<form>....
....
<a wicket:id="resetKey">Give me another key</a>
....
</form>
I want response to onClick of "resetKey", jump back to #setup. I don't
understand how to use Link#getAnchor(), Link#setAnchor(Component c) do
this. Please help.

Javascript is fine. But I am not using FeedbackPanel. I am pulling the
error message out from FormComponents and show them along side it. Can I
just query the session to see if it has any error? If so, where and how to
insert his code and do the "spit out some javascript"? And what is the
javascript? "location.hash='setup'"?
