I use both of those. I've started playing with wicket because Gavin recommends JSF or wicket (both have component models). wicket doesn't appear to have active component libs like richfaces, primefaces, icefaces.
I'm surprised that richfaces adores mojarra. The lists http://java.net/projects/javaserverfaces/lists have low activity. Issues http://java.net/jira/browse/JAVASERVERFACES/ seem to get resolved. I can only dream of a framework: * Reliable on gae. * Several component lib developers conforming to an open look&feel std like nimbus. * Client-side validation first to avoid server load & bandwidth for silly mistakes like not filling in a required field.
