RichFaces JSF 1.2 compatible starting from 3.2.0 version. So compatibility matrix for 3.3.0 release are actual for 3.2.2.
Version 3.3 documentation states that WAS 7.0 is required. So are you saying version 3.2.2 GA also requires WAS 7.0?
Is the documentation for older versions (e.g. 3.2.2 GA) available on the JBoss site?
