I'm not keen on the named context parameters idea. There's a
persuasive argument for putting filter parameters into the query
string portion of the URL instead of in the context. http://blpsilva.wordpress.com/2008/04/05/query-strings-in-restful-web-services/
So you get a URL like this
http://localhost:8080/myapp/mypage?firstname=Humpty&lastname=Dumpty
instead of this
http://localhost:8080/myapp/mypage/firstname/Humpty/lastname/Dumpty
It's easy enough to do:
@Inject
private ComponentResources _componentResources;
@Inject
private Request _request;
public Link set(String firstName, String lastName) {
Link link = _componentResources.createPageLink(this.getClass(),
true);
if (firstName != null) {
link.addParameter("firstname", firstName);
}
if (lastName != null) {
link.addParameter("lastname", lastName);
}
return link;
}
void onActivate() {
_firstName = _request.getParameter("firstname");
_lastName = _request.getParameter("lastname");
}

I tend to try and keep all my pages as stateless as possible, you
can then quite easily require a few query string parameters per page
when this is the case, consider the case of browsing a storefront -
you need a "category id" (e.g. books, shoes), a page number (for the
current page if looking at paginated data) and a "sort by" field
(for the clients sort by selection). Already we have 3. There can
easily be more, say if the client is "filtering" the view.

I try to keep my pages as stateless as possible (thus
bookmarkable) and better support for "named" context variables
would make this much easier.
I haven't missed named context parameters because my pages, almost
all the time, need just one parameter, sometimes two, so there is
no need to name them.
