"IllegalArgumentException: JBAS018062: Specified attribute cannot be replicated" when using RichFaces push in distributable application

Issue

After making our application distributable across the cluster we are seeing errors dealing with the richfaces push servlet. We create our push topics in a session scoped backing bean (UserBean).

The application works as expected as long as our .war is not marked as distributable. The push functionality seems to work fine despite the errors.

Servlet.service() for servlet Push Servlet threw exception: java.lang.IllegalArgumentException: JBAS018062: Specified attribute cannot be replicated
