Event Listener Not Working Without Administrative Session

Hello Everyone,

I am writing an EventListener but the onEvent() method is not getting called if I create the session by doing below:

Map<String, Object> param = new HashMap<>()
param.put(ResourceResolverFactory.SUBSERVICE, "SUBSERVICENAME")
resourceResolver = resourceResolverFactory.getServiceResourceResolver(param)
session = resourceResolver.adaptTo(Session.class)

however if I am creating the session by "repository.loginAdministrative(null)" the class is working as expected and the onEvent() is getting called. The latest example in the ACS Commons github is also getting the session by "repository.loginAdministrative(null)".
https://github.com/Adobe-Consulting-Services/acs-aem-samples/blob/master/bundle/src/main/java/com/adobe/acs/samples/events/impl/SampleJcrEventListener.java

But it is not advisable to use repository.loginAdministrative(null) to obtain the session, not to mention its also deprecated. I was just wondering if anyone have faced this before and have some possible solution.

Thanks and Regards,

Tuhin

    This looks like a bug. I would file a ticket to let the team know this is not working. LOoks like you are doing everything you are suppose to do.

    Hi Scott,

      Hi,

      Rather than using EventListener I started using the EventHandler which gives you the same functionality as event listener.

      Thanks

      Guys, I realized the problem was in resourceResolver property. In my case when the property was local in activator, it did not work.

      When the resourceResolver property is global in class, then it works.

       

      Following works:

       

      @Activate
public void start(BundleContext context) throws Exception {
    resourceResolver = resolverFactory.getServiceResourceResolver(null);
    session = resourceResolver.adaptTo(Session.class);
    observationManager = session.getWorkspace().getObservationManager();
    listener = new Listener(session);
    observationManager.addEventListener(listener, ...

      Following does not work:

      @Activate
public void start(BundleContext context) throws Exception {
    ResourceResolver resourceResolver = resolverFactory.getServiceResourceResolver(null);
    session = resourceResolver.adaptTo(Session.class);
    observationManager = session.getWorkspace().getObservationManager();
    listener = new Listener(session);
    observationManager.addEventListener(listener, ...

      It is weird and does not make much sense to me, but making resourceResolver class variable instead of method local solves it.
