Examples of javax.portlet.faces.BridgeEventHandler

javax.portlet.faces.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 method on the BridgeEventHandler instance passed to it (via a PortletContext attrbiute at init 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.
