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.

Hi Christian,
take a look at [1]. That describes the steps for Tomahawk custom

Hello,
how can I use custom JSF components with Facelets? I have some JSF
components which I wanna use in my Facelets-Web-App.
Is there any example or something like that?
regards,
Christian
