Thanks, guys.
I think I was over-thinking this. I've decided to do this with pure
Javascript included on every page, just giving focus to the first
non-disabled input element. Igor's comment about metadata made me realize
I was already tagging invalid fields with invalid in the class
attribute, so I keyed off that to give those fields priority. I also use
the CSS class name nofocus to avoid always giving focus to a search
input at the top of each page.
I've attached the JS if anyone's interested. It won't give focus to a
select or textarea, but I don't need that just now.

You may already know the quick un-generic way to do this - but for example
this is what I have on a login page where I set focus to the password
field
in case the user-id field is already filled in.
getBodyContainer().addOnLoadModifier(new AbstractReadOnlyModel() {
public Object getObject() {
String markupId;
if(loginName.getConvertedInput() == null) {
markupId = loginName.getMarkupId();
} else {
markupId = password.getMarkupId();
}
return document.getElementById(' + markupId + ').focus();
}
}, password);

you can set some metadata into these components. have your page/form
subclass implement iheaderresponse, traverse the hierararchy in
renderhead
and set focus to the first component with the right metadata through the
header response that is passed in.
sounds like a mouthful, but should be pretty simple to implement.

Hi folks,
I'm new to Wicket and I'm wondering if there's a Wicket way to have
input focus set to the first form component on the page. I could
always
code up some
Javascript to do this but it would be nice if I could flag certain
form
components as wanting focus, then have the page set the focus to the
first of these. Ideally, if any form components had failed validation,
the
page would ignore the wanting focus flag and give focus to the first
invalid field.
Any ideas?
