It seems Seam 3 team does not want to maitainate the Seam 2 UI components in Seam3, it suggest users to upgrade UI to richfaces 4 directly...
Is there a official guide to upgrade Seam2 UI to the latest Richfaces 4 components?
Such as s:fragment=>a4j:outputPanel
s:fileUpload=>rich:fileUpload
s:graphicImage=>mediaOutput and h:graphicImage
