Neil Griffin updated PLUTO-702:
-------------------------------
Description:
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.
