I think I had a similar problem when I first tried to use JSCookMenu with Seam and Facelets. The problem though appeared not to be about Seam, it was Facelets instead. You have to explicitely declare all Tomahawk components if you use Facelets. See MyFaces Wiki: http://wiki.apache.org/myfaces/Use_Facelets_with_Tomahawk A rendering class for JSCookMenu must be declared, otherwise nothing renderers to the view.
