Using Seam with Lilya JSF components

[jmoreira]

My company has been using Seam2 and Richfaces but we are looking for some alternatives to complement RichFaces and i came across LiLya (JSF ExtJS) (http://sharesource.org/project/lilya/) and have been trying to setup a seam2 project with it, without success. The Lilya examples use plain JSP's but we are using Facelets, are they compatible? Anyone has setup a Seam project  with it?
The Lilya tags aren't rendered (it's jar contains a faces-config.xml) ? What could it be the problem?

If you use a new JSF component library, you have to have a Facelets tag library file that exposes that library.

Hi,

yes i found it on their latest SVN rev.
Now (and then also) the problem is that they depend on old ajax4jsf which now is merged into RichFaces but was re-factored, resulting on java.lang.NoClassDefFoundError's:
