This very minute I'm refactoring: LinkFactory is going away, but
there's a single service, ComponentEventLinkEncoder that's responsible
for encoding and decoding component event and page render requests.
Awesome! Specially if some crucial method receives a Request. That will
make the missing part of URL rewriting (the generated links) a piece of
cake.
It's a public service, so it will be something people can override.
Override or decorate. :) The power of decorating services is something
that I've been discovering lately. For Tapestry CRUD, I wrote a simple
service (BeanModelCustomizerService) that decorates BeanModelSource and
provides the ability of customizing BeanModels for a given type in a
single place (a BeanModelCustomizer instance). Thus, if I have a listing
page (Grid), an edition page (BeanEditForm/BeanEditor) and a view page
(BeanDisplay), I don't need to copy the customizing of the BeanModel in
the three pages nor use the model parameter of this components. Less code
in the end, more magic. :)
