Hello, I've just implemented a trivial TreeCacheListener implementation. It extends AbstractTreeCacheListener, and only implements two methods: nodeRemoved(Fqn) and nodeRemove(Fqn, boolean, boolean). When I create the listener, I register it with the treecache as shown below: TreeCache treeCache = new TreeCache(); PropertyConfigurator config = new PropertyConfigurator(); config.configure(treeCache, PROPERTIES_PATH); MyCacheListener listener = new MyCacheListener(); treeCache.addTreeCacheListener(listener); treeCache.start(); In the cache configuration, I use INVALIDATION_SYNC as CacheMode. When I modify an object in one node of my cluster, the call is issued as expected. The nodeRemoved(Fqn) method is called. My problem is that I always recieve a null Fqn parameter in the nodeRemoved(Fqn) method. Is there something that I should do, besides register the listener, to recieve a correct Fqn? Or is it expected that, in some situations, a null Fqn should be recieved?
