------------------------------------

I've tried to reproduce the bug without success. 
Could you provide a test project?

>          Issue Type: Enhancement
>          Components: CDI integration
>    Affects Versions: 5.0.0.CR8, 5.0.0.FINAL, 5.1.0.FINAL
>         Environment: infinispan-cdi 5.1.0-SNAPSHOT, jboss AS 7 (all libs packaged within ear)

> I'm trying to get the CDI examples to work on an app. so I've created this config:
> @Produces
> 	@ApplicationScoped
> 	@OverrideDefault
> 	public EmbeddedCacheManager getCacheManager() {
> 		GlobalConfiguration gc = GlobalConfiguration.getClusteredDefault();
> 		gc.fluent().transport().clusterName("shared-cache-cluster").addProperty("configurationFile", "jgroups-tcp.xml");
> 		Configuration c = new Configuration().fluent().clustering().mode(CacheMode.REPL_ASYNC).build();
> 		return new DefaultCacheManager(gc,c);
> 	}
> BTW, trying to use configuration and @Infinispan with this I get an error when CacheManager tries to get the cache, I've discussed it at http://community.jboss.org/thread/171005?tstart=0
> Well, my scenario has 2 apps one on each node. So in one node I put a value in the distributed cache, and I expect to receive an event on the other node.
> My problem is that the events for a cache are only hooked when the cache is first accessed (According to CacheManager:getAdvancedCache).
> So, in my second ear, if there's no "warm-up" of the cache, the events do not get hooked and I don't get any notification.
> So I tried to use a Singleton:
> @Singleton
> @Startup
> public class CacheWarmupBean(){
> @Inject Cache<String,String> cache;
> @PostConstruct
> void warm(){
> cache.getCacheName();
> }
> }
> Problem is that the bean gets started before the extension, and no target is found for the cache.
> I wonder, is it possible to either warmup the cache on a different way or hook the events?
