Add dispatching to action configuration
---------------------------------------
Key: STR-3168
URL: https://issues.apache.org/struts/browse/STR-3168
Project: Struts 1
Issue Type: New Feature
Components: Core, Extras
Reporter: Paul Benedict
Assignee: Paul Benedict
Fix For: 1.4.0
Based on the discussions of STR-2940 and the general trend of the industry, the
correct place for a framework to support dispatching is not in the Action, but
as part of the Controller. The Action can do anything it wants once it has the
request, but the support belongs to the framework.
The following changes are proposed:
* Introduce a Dispatcher interface that accepts the current ActionContext and
returns an Object
* Add @dispatch to the <action> element
* Either modify ExecuteAction or create subclass that executes the action by
delegating to the Dispatcher interface
* Object is then marshalled into an ActionForward through a conversion process
* Retrofit ActionDispatcher with the interface
