Stop receiving notification from a node (pubsub)

Hello,
I'm wondering why I'm receiving the same notification every time I login to the server from the node I subscriped ??

I thought that, I will receive the notification just one time unless there is a new published Item on the node.

Here is my code of node creation :

con.connect();  con.login();  PubSubManager pm = new PubSubManager(con);  ConfigureForm form = new ConfigureForm(Type.submit);  form.setAccessModel(AccessModel.open);  form.setDeliverPayloads(true);  form.setNotifyRetract(false);  form.setPersistentItems(false);  form.setPublishModel(PublishModel.subscribers);  LeafNode node = (LeafNode) pm.createNode("sameh" ,form);

]publishing Item to the node "sameh" :

Publishing payload item :

   LeafNode node = pm.getNode("sameh");  SimplePayload spa = new SimplePayload("samehId", "pubsub:categories:sameh"  , "<samehId xmlns='pubsub:categories:sameh'><hello>sameh2200099990000</hello></nnaassCategoryId>");  PayloadItem<SimplePayload> item = new PayloadItem<SimplePayload>("A7",spa);  node.send(item);

Listening and subscription :

LeafNode node = pm.getNode("sameh");
node.addItemEventListener(new ItemEventListener<Item>() {
public void handlePublishedItems(ItemPublishEvent<Item> items) {
System.out.println("items count --- " + items.getItems().size());
List<Item> its = items.getItems();
Item i = its.get(0);
System.out.println(i.toXML());
}
});
node.subscribe("admin@sameh-desktop");

Every time I login, this listener works and notify me with the same item I saw before.

Is there a way to prevent receiving the the same notification ?
I know that I can ignore the notifaction I saw accourding to my local db (or somehow).

But I need to find a way to prevent the server to send me the same notifcation in order to maintain the bandwidth.
