At http://snapshots.jboss.org I find 4.0.0 snapshots for richfaces-api and richfaces-impl. However, I cannot find a 4.0.0 snapshot for richfaces-ui.
Any hint is appreciated!
We are still in the process of setting up the build system to update the snapshots, and get everything ready for first consumption. We'll post when this is all ready.
Thanks for looking though :-)
