- For those needing DispatchAction capabilities while using your own base Action, the solution is the new [http://struts.apache.org/api/org/apache/struts/actions/ActionDispatcher.html ActionDispatcher] class that was introduced in Struts 1.2.7.  It provides DispatchAction functionality without having to inherit from a particular class, and can be extended to provide custom Dispatch behavior.
+ For those needing !DispatchAction capabilities while using your own base Action, the solution is the new [http://struts.apache.org/api/org/apache/struts/actions/ActionDispatcher.html ActionDispatcher] class that was introduced in Struts 1.2.7.  It provides !DispatchAction functionality without having to inherit from a particular class, and can be extended to provide custom Dispatch behavior.

+ For those wanting more than !DispatchAction can provide the solution is [http://wiki.apache.org/struts/ActionDispatcher ParameterListActionDispatcher] class.  It provides all !DispatchAction functionality and more:
+    * One action mapping can contain several event definitions.
+    * Submit buttons can have any caption; caption can be changed in runtime.
+    * No event-to-method map is needed.
+    * Action method name can be either used directly on a web page, or can be aliased with an event name.
+    * It is possible to define a default method if event is not recognized.
+    * If event is not recognized and default method is not defined, the dispatcher invokes {{{unspecified}}} method.
+    * Standard Cancel buttons is hooked up to {{{cancelled}}} method and does not have to be defined explicitly.
