ActionListener versus Action

Action method is used to perform navigation and ActionListener is used to perform some logic in backing bean.While it is possible to define a backing bean method that performs navigation and binds the method to the actionListener attribute, this is not best practice. Instead, application logic should be placed in the backing bean method to which the actionListener is bound. Following successful execution of that method, the ADF Faces lifecycle will call the method or control flow case specified by the action attribute. If the method bound to the actionListener fails, developers can change the action outcome to suppress navigation so that the user has the opportunity to correct the issue.
