public class Action

extends AbstractFacesController

This Controller executes the actions defined by the property actions or fromAction respectively. It uses the NavigationHandler to render the appropriate view (resolved by an outcome and the corresponding navigation rule).

Workflow

1. execute the actions (must be method bindings) if not empty
2. whether execute the fromAction (if it's a method binding and not null) or use it as an outcome if it's a string
3. navigate with the help of the NavigationHandler and the evaluated outcome to the proper view and render it (the outcome of the last executed actions method binding is used if fromAction is null)

Exposed configuration properties:

name	default	description
actions	Collections.EMPTY_LIST	method bindings returning an outcome (public String doBar(){...}), e.g. #{foo.doBar}
fromAction	null	method binding returning an outcome (public String doBar(){...}), e.g. #{foo.doBar}, or a simple outcome (represented by a string)
