Listener gets events twice 2.2.0.CR7

[mbrade]

Hello

I'm using JBossCache 2.2.0.CR7 with one CacheListener on the Cache. The cache runs fine but my problem is that I get all events twice.

What I do is:

 Cache cache = ...get the Cache from Spring Context...
 cache.addCacheListener( new KeyEvictionListener() );
 cache.create();
 cache.start();

My CacheListener:

import org.jboss.cache.notifications.annotation.CacheListener;
import org.jboss.cache.notifications.annotation.NodeActivated;
import org.jboss.cache.notifications.annotation.NodeCreated;
import org.jboss.cache.notifications.annotation.NodeEvicted;
import org.jboss.cache.notifications.annotation.NodeLoaded;
import org.jboss.cache.notifications.annotation.NodeMoved;
import org.jboss.cache.notifications.annotation.NodePassivated;
import org.jboss.cache.notifications.annotation.NodeRemoved;
import org.jboss.cache.notifications.event.Event;
import org.jboss.cache.notifications.event.NodeCreatedEvent;
import org.jboss.cache.notifications.event.NodeEvictedEvent;
import org.jboss.cache.notifications.event.NodeRemovedEvent;

@CacheListener
public class KeyEvictionListener {

 @NodeRemoved
 @NodeEvicted
 @NodePassivated
 @NodeCreated
 @NodeMoved
 @NodeActivated
 @NodeLoaded
 public void handleEvent(Event cacheEvent){
 System.out.println("got event: "+cacheEvent.getType().name());
 switch( cacheEvent.getType() ){
 case NODE_REMOVED : {
 NodeRemovedEvent nodeRemovedEvent = (NodeRemovedEvent)cacheEvent;
 System.out.println( nodeRemovedEvent.getFqn() );
 System.out.println( nodeRemovedEvent.getData().toString() );
 break;
 }
 case NODE_EVICTED : {
 NodeEvictedEvent nodeEvictedEvent = (NodeEvictedEvent) cacheEvent;
 System.out.println( nodeEvictedEvent.getFqn() );
 break;
 }
 case NODE_CREATED : {
 NodeCreatedEvent nodeCreatedEvent = (NodeCreatedEvent) cacheEvent;
 System.out.println( nodeCreatedEvent.getFqn() );
 }
 }
 }

}

I'm using two regions one with an EvictionPolicy and one which contains resident Nodes only.

If I run some TestCode i get the following output:

got event: NODE_CREATED
/mc
got event: NODE_CREATED
/mc
got event: NODE_CREATED
/mc/entries
got event: NODE_CREATED
/mc/entries

got event: NODE_EVICTED
/mc/keys/5f8d866c3800d096698dc48b549e4dd3
got event: NODE_EVICTED
/mc/keys/5f8d866c3800d096698dc48b549e4dd3
got event: NODE_EVICTED
/mc/keys/5755b475601346aa24776baa12da9dfe
got event: NODE_EVICTED
/mc/keys/5755b475601346aa24776baa12da9dfe

As you can see all Events come twice for the same Fqn.
Is it a bug or am I doing somthing wrong?

thanks for the help

The event is being triggered before creating the node and after the node is created. You can determine that by using Event.isPre() method.
