Example 10 with NavigationHandler

use of javax.faces.application.NavigationHandler in project spring-framework by spring-projects.

the class DecoratingNavigationHandler method callNextHandlerInChain.

/**
	 * Method to be called by subclasses when intending to delegate to the next
	 * handler in the NavigationHandler chain. Will always call the most
	 * appropriate next handler, either the decorated NavigationHandler passed
	 * in as constructor argument or the original NavigationHandler as passed
	 * into this method - according to the position of this instance in the chain.
	 * <p>Will call the decorated NavigationHandler specified as constructor
	 * argument, if any. In case of a DecoratingNavigationHandler as target, the
	 * original NavigationHandler as passed into this method will be passed on to
	 * the next element in the chain: This ensures propagation of the original
	 * handler that the last element in the handler chain might delegate back to.
	 * In case of a standard NavigationHandler as target, the original handler
	 * will simply not get passed on; no delegating back to the original is
	 * possible further down the chain in that scenario.
	 * <p>If no decorated NavigationHandler specified as constructor argument,
	 * this instance is the last element in the chain. Hence, this method will
	 * call the original NavigationHandler as passed into this method. If no
	 * original NavigationHandler has been passed in (for example if this
	 * instance is the last element in a chain with standard NavigationHandlers
	 * as earlier elements), this method corresponds to a no-op.
	 * @param facesContext the current JSF context
	 * @param fromAction the action binding expression that was evaluated to retrieve the
	 * specified outcome, or {@code null} if the outcome was acquired by some other means
	 * @param outcome the logical outcome returned by a previous invoked application action
	 * (which may be {@code null})
	 * @param originalNavigationHandler the original NavigationHandler,
	 * or {@code null} if none
