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)

Thanks,
i created the Facelets-Taglib-File, but it still don't work. It would be
great if somebody could tell me what I do wrong. See my source code below.
Thanks.
