We've tested 4.0.0.CR1 on Mojarra 2.0.4 and 2.1.0 and it worked. What application server do you use?
2.0.2 is seriously out dated, so I won't recommend it.
my server is websphere 7.0 i make a shred lib as i told you it works if it was 2.0.4 but it is not working on 2.0.10, can i work on 2.0.4 for richfaces 4 or there is a limitation for it.
but it works on Tomcat 6 .
Yes, 2.0.4 is ok. Have you tried with WebSphere 8 beta BTW?
