As you all know the Richfaces project is winding down. My project is using Richfaces 4.5.x and running on Wildfly 8.0.0 Final. Does it mean the future releases of Wildfly will stop supporting the Richfaces library.
I have zero experience in RichFaces. However, based on my limited knowledge of it, it's just another JSF component library and as such there's no specific integration with it in WildFly. You just use it as if it were some library your application needed. WildFly support JSF standard and as such, I think, you should be able to continue to use this library.
