Ok, is anybody actually using rich:tree with seam???! Putting richfaces in both server/lib *and* WEB-INF/lib gets rid of the deployment errors - but as expected, will throw a classcast-error when rendering the tree: java.lang.ClassCastException: de.vierundsechzig.springer.platform.action.structure.ContainerNode cannot be cast to org.richfaces.component.TreeNode So, I'm still looking for a proper place for the richfaces-lib (any other idea then tearing the lib apart and putting the TreeNode in its own jar would be highly appreciated!!) cheers stf View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4060756#...
