Re: [gatein-dev] PortletApplicationDeployer listeners

That's fine, initially it didn't seem like the same listener instances would be applied to all deployments, not a problem. In terms of retrieving the portlet filter instance to actually perform injection on, is there a cleaner way to get it than this: filterClasses.add(ActionFilter.class); filterClasses.add(EventFilter.class); filterClasses.add(RenderFilter.class); filterClasses.add(ResourceFilter.class); ManagedPortletFilter managedPortletFilter = (ManagedPortletFilter) managedObject; PortletFilterImpl portletFilterImpl = (PortletFilterImpl) managedPortletFilter.getPortletFilter(); PortletFilter portletFilterInstance; for (Class type : filterClasses) { portletFilterInstance = (PortletFilter) portletFilterImpl.instance(type); // If not null, then use it and skip rest of loop } Thanks Ken From: "Julien Viet" <julien(a)julienviet.com&gt; To: "Ken Finnigan" <kfinniga(a)redhat.com&gt; Cc: gatein-dev(a)lists.jboss.org Sent: Tuesday, April 9, 2013 8:12:20 PM Subject: Re: [gatein-dev] PortletApplicationDeployer listeners Yes it is expected. The listener may want to be aware of all deployments (for maintaining a registry of all portlets with a single listener instead of adding/removing N listeners where N is the number of deployments). This is similar to the JMX JMImplementation MBean that send notifications about MBean life cycle for any MBean added/removed from the MBeanServer as the intent is originally the same. What is wrong with having a single listener if you can associate the CDI meta data with the deployed portlets ? I would proceed in two steps : 1/ upon deployment : prepare the CDI info for all portlets and add to a map a list of portlet id -> cdi meta data for the portlet (injection etc…) 2/ upon portlet created event : lookup for cdi work to do from portlet id and if it exists then honour the cdi integration On Apr 9, 2013, at 10:14 PM, Ken Finnigan <kfinniga(a)redhat.com&gt; wrote: All, In implementing CDI injection into GenericPortlet and PortletFilter instances, I had assumed that I could add a ManagedObjectRegistryEventListener, specifically for CDI processing, and add it to the broadcaster in PortletApplicationDeployer for only those PortletApplicationDeployment's that needed CDI injection. ie. the listener would be added before creating a PortletApplicationDeployment and then removed straight afterwards to ensure that portlet deployments that had nothing to do with CDI, were not calling the listener for all event notifications for no reason. An unexpected consequence of this is that I've discovered the broadcaster list of listeners is the exact same instance across all PortletApplicationDeployment instances. So when I removed the CDI listener from broadcaster on PortletApplicationDeployer, it also removed that listener from the PortletApplicationDeployment that had just been created. Is that expected? I'd find it unusual that its not possible to add a listener specific to a deployment that should not be applied to all of them. Wondering if ManagedObjectRegistryEventBroadcaster needs to support cloning to facilitate this functionality? Any other thoughts on a better way to do this are appreciated, as I certainly feel it unnecessary to defensively code my listener for all types of portlets it can be attached to when it doesn't need to.
