Are there any facilities in sling for registering jcr event

Both the external javax.jcr.observation.EventListener and the
SynchronousEventListener type.
No we don't have extra support in Sling atm. One of the problems
here is
that the jcr listeners are tied to a session.
But we're working on a resource based eventing which leverages the
OSGi
eventing:
https://issues.apache.org/jira/browse/SLING-944
I am after is a listener that only fires on the cluster node that
created it. I need this because I want to ensure that all nodes,
however they are created have certain properties (like the id of the
creator) if appropriate.
The only way I have found to do this is a SynchronousEventListener,
however this is internal to Jackrabbit and so its not possible to
activate a bundle containing this.
The SLING-944 patch starts to get close, but its bound to
EventListener so one copy of the event will fire on all nodes in a
cluster, depending on how the OSGi Event admin service is wired this
might mean that you will see duplicates of the event in a cluster.....
so your use case may be the same.
(btw, I agree, the session binding is not ideal for general purpose
events that have no connection to jcr)
