THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
The ActionProxy obtains the Action class and calls the appropriate method. By default, Actions are obtained through local instantiation, but an Action could also be obtained remotely if an alternative ActionProxy were provided.
An alternative ActionProxy can be configured through ActionProxyFactory. Typically, an ActionProxy will utilize the ActionInvocation to encapsulate the execution of a particular request.
The ActionInvocation determines how an Action is handled: Is it being intercepted? Is there a PreResultListener acting on it?
Essentially, ActionProxy encapsulates how an Action can be obtained. ActionInvocation encapsulates how the Action is executed when a request is invoked
ActionProxy acts as a representation proxy that is responsible for executing a particular Action. This is such that one could have different means of getting an action. Its customizable through ActionProxyFactory.
ActionInvocation represents a particular action invocation and is customizable through ActionProxyFactory as well. It represents how an action is to be executed (eg. having it intercepted, then execute it, having PreResultListener acting on it before the Result is being executed etc).
