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.
