RichFaces is a component library for JSF and an advanced framework for easily integrating AJAX capabilities into business applications.

• 100+ AJAX enabled components in two libraries
• a4j: page centric AJAX controls
• rich: self contained, ready to use components
• Whole set of JSF benefits while working with AJAX
• Dynamic resources handling
• Testing facilities for components, actions, listeners, and pages
• Large and active community

We are working hard on RichFaces 4.0 which will have full JSF 2 integration. That is not all though, here is a summary of updates and features:

• Redesigned modular repository and build system.
• Simplified Component Development Kit with annotations, faces-config extensions, advanced templates support and more..
• Ajax framework improvements extending the JSF 2 specification.
• Component review for consistency, usability, and redesign following semantic HTML principles where possible.
• Both server-side and client-side performance optimization.
• Strict code clean-up and review.
