The topic of CSS and JS are very deep and you could spend months trying to come up with "the ultimate solution". Instead, I suggest you come up with simple use-cases that depend on CSS and JS, design Wicket for those cases and incrementally increase the complexity of the use-case.
You don't necessary need to handle all use-cases anyway. Just
get a slick design going for the most common use-cases and grow from
there.
have some idea how the simple case might evolve, even if that isn't implemented in 1.0.
Personally, I think the best way to start is by forcing all CSSthis sounds like a good start and that seems like the right way to add links, but i want to avoid
and JS to be found on separate pages (that is, we don't support inline
CSS/JS at this time). If components associate a JS or CSS component
with themselves (using add() or some other mechanism) then at Page
rendering time, the Page walks through all subcomponents recursively,
picks up their JS/CSS dependencies and automatically outputs links to
those external CSS/JS pages at the top of the page. The JS/CSS files
are also dynamically generated.
any kind of file generation. better to add the code inline, even if the problem is a little harder.
That's probably far from being a perfect solution, but it's a
fairly clean beginning and we could work from there. The way I see it,
JS/CSS are "peers" of a Wicket component. In a sense, the markup (html)
of a Wicket component is somewhat of a peer itself. Does this make
sense?
yup.

okay, why don't we start brainstorming our requirements for this?
a few things that occur to me:
- components ought to be able to contribute javascript methods to the header section
- adding javascript needs to be smart in terms of merging things. if a javascript function already exists, it should be left alone
- ordering of contributions is going to be important, particularly in css
- could make javascript contributions modular via .js files included with the <script src="foo.js"/> syntax
- javascript .js files could be loaded in the same way that markup files are loaded via resource locator code
- need support for easily adding javascript invokations to various html attributes
- client side validation should be added through the existing validation api, which should contribute javascript code to the header and the form button onclick handler
i don't have deep javascript knowledge, so everyone's embellishments and thoughts are extra important.
some examples of common javascript tasks as well as ideas about how things might best work would be helpful.
