> Key: PLUTO-702
> URL: https://issues.apache.org/jira/browse/PLUTO-702
> Project: Pluto
> Issue Type: Bug
> Components: demo portlets
> Affects Versions: 3.0.0
> Reporter: Neil Griffin
> Assignee: Neil Griffin
> Priority: Major
> Fix For: 3.0.1

>
> Section 20.1 of the Portlet 3.0 Specification states:
> {quote}
> When the portlet container uses the CDI container to instantiate the portlets, it must respect
> any scope annotations on the portlet beans. Generally, portlets should be @ApplicationScoped in order to avoid unnecessary object creation and destruction.
> It should be noted that regardless of the bean scope, the Portlet interface init(PortletConfig) method will only be called a single time when the portlet is taken into service. If the portlet bean scope is other than @ApplicationScoped or @Dependent, this can potentially lead to unintended effects. Portlets that do not directly or indirectly implement the Portlet interface can use the CDI @PostConstruct and @PreDestroy annotations to properly handle bean initialization and tear down. A PortletConfig object can be injected as necessary.{quote}
> Since all of the portlet classes annotated with {{@PortletConfiguration}} in the PortletHubDemo extend {{GenericPortlet}}, they indirectly implement the {{Portlet}} interface. This means that the "unintended effects" can happen in various portlet containers.
> Because of this, it is necessary to annotated each of these classes with the {{@ApplicationScoped}} annotation.
