public interface BridgeEventHandler
The BridgeEventHandler
interface defines the class the bridge relies on to process portlet events.
Because portlet events have arbitrary payloads the bridge provides no automated mappings to managed beans. Instead,
the bridge calls the handleEvent(FacesContext, Event)
method on the BridgeEventHandler
instance
passed to it (via a portlet context attribute at initialization time. This method is expected to update any models
based on the event's payload and then to perform any needed application recomputation to ensure a consistent state.
The method is called after the FacesContext
has been established and the Lifecycle
has restored the view.
A view navigation can be affected by returning a non-null EventNavigationResult
. Such an object will
contain two String
values: a fromAction and an outcome. These correspond to the from action and outcomes
in Faces navigation rules. Using this information the bridge affects the navigation by calling the Faces NavigationHandler
.

handleEvent(javax.faces.context.FacesContext facesContext,
javax.portlet.Event event)
Called by the bridge when it needs to process a portlet event.

facesContext
- The current Faces context. A Lifecycle has been acquired and the current view restored.event
- The portlet event. Other portlet information (request/response) is accessed via the ExternalContext
