We found a way to make it work, could you try this snapshot to check if it's now working as expected ?
The underlying issue is that Jboss does not seem to always trigger notifications for beans that are in the boss.as domain, but if you configure it with jboss.as.expr it should work. The fix in the snapshot just applies a fallback to detect when the bean is added, so you just can use the beans as you see them in jconsole.
