Hi, I'm talking about the regular Cache (TreeCache), not PojoCache. It seems that if I try to use the Node interface directly (after getting some sub-node from the Cache interface), in optimistic locking mode, a simple node.put(k, v) will not make a subsequent node.get(k) return v. However, if I work against the Cache interface directly, it seems to work fine. So... 1) What do you say? Is this true, or am I missing something? 2) Can I at least rely on node additions (e.g. addChild()) to reflect immediately? 3) If I want to iterate on the node contents (presumably using Node.getData() ) - and make sure the recent changes are reflected - how can I accomplish that? The Cache interface does not offer me an alternative for that... View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3997664#...
