Questions tagged [jsf-2.2]

JavaServer Faces 2.2 is the major JSF upgrade that's part of Java EE 7. It has some significant new features like task flows (Faces Flow), a stateless mode, basic theming (resource library contracts), build-in HTML5 support and a much improved "bare HTML" mode (passthrough elements). Starting from this version, JSF formally supports CDI and for some features even depends on CDI.
