Ok, so after discussing this further with Bela and Jason earlier, I've updated the wiki. Could you guys please have a look and make sure we're all on the same page here. Basically, the big changes are: | * Idempotency is required, but we've determined that cache updates are idempotent provided updates are applied in order. | * No more proxying of local calls on the state provider. | * No more locking of local transactions from committing for the duration of state generation. | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4136108#...
