RichFaces 5 compatibility with JSF 2.1 or with RF4 ?

Hello all, during investigating [RF-13348] pickList - columnClass attribute behaves differently than in RF4 - JBoss Issue Tracker (https://issues.jboss.org/browse/RF-13348) I have found out that RichFaces 5 +pickList+ attribute +columnClass+ is incompatible with the RichFaces 4 one. However, according to Brian, the RF5 one behaves as JSF 2.1. dictates. What will be our strategy for this ? Will we adhere JSF 2.1 or the previous releases ? Thanks Juro Posted by forums Original post: https://community.jboss.org/message/845869#845869
