running Richfaces in a clustered environment.

I currently have a small tomcat cluster running with session replication.

javax.faces.STATE_SAVING_METHOD is set to server

When a user hits a page org.ajax4jsf.application.AjaxStateManager.VIEW_STATES_MAP is created on all nodes in the cluster.

When that user hits a second page VIEW_STATES_MAP is only updated on 1 tomcat instance.

How can I get all updates to VIEW_STATES_MAP to replicate across the cluster ?

So, what is your claster configuration ?
For a Tomcat 5.5 ( http://tomcat.apache.org/tomcat-5.5-doc/cluster-howto.html ), concurrent request from same session for a different claster nodes can override changes on other nodes.
Also, Tomcat claster service can have a different replication modes ( sync, async, pooled ).
So, there is recomendation for a claster front-end balancer : request for a same session must be served by one claster node.

It has been confirmed there is a cluster bug in jsf-ri 1.2_06.

Look for the soon to be released jsf-ri 1.2_07.
