alright, again. version 2
I reviewd the documentation on annotations and simplified the .jwc
I still want to know how to add a component to a library without a jwc file?

Alright, I had reason to stay up anyhow.
Attached is a version of a NameLink component that takes a name
parameter. Tapestry 4. I've tested this component only on
linux/firefox at home, but the same technique has been working on our
site for the last few months; I'll test this component out on a few
other browsers tomorrow. Anyone can feel free to absorb this into
Tapestry.
comments?
Questions: I'm trying to learn how to get rid of the jwc. Anybody know
the last few things I need to do? ReservedParameters through
annotations, and how to add a component to a component library without
refering to a jwc.

I couldn't read through the threads ( didn't seem like the right
solution anyhow ). This is what our html developer came up with, a
nice javascript hack: (right off of our site) He simply created a
javascript function that is called that does the named-anchor
dereference, instead of letting the anchor-link do it (which takes
into account base-href).
<!-- don't reload the page when linking to anchors... -->
<script type="text/javascript">
function anchorMessages(){
location.hash = "messages";
}
</script>
<a href="javascript:anchorMessages()">blah</a>
Wow I just realized that I could easily make a component to wrap this.
I'll see about that in work tomorrow, or if someone else feels like
it, should be pretty darn easy.

There is a lot of info on this topic. Just do a search for "anchor
