You can also download my ANT plug-in that generates taglib.xml files
from a TLD file [1 & 2]. It is what I used to get started using
Tomahawk with facelets. I hand modify it now that it is done, so let
me know if you use it and find any issues. Check out the "all" release
for the source code and an example.

Hi,
I think the issue is that your component is rendering itself, which
you shouldn't do.
(or can you try null for the renderer-type node?)
It is better to provide a renderer for your component (better reuse of
the component).
After all use these nodes in the taglib.xml file
<component-type />
<renderer-type />
one cool thing with facelets is, that you don't need to write a tag,
(since that guy is only for the jsp world of jsf)
