Prototypical actions
--------------------
Key: STR-3067
URL: https://issues.apache.org/struts/browse/STR-3067
Project: Struts 1
Issue Type: New Feature
Components: Core
Reporter: Paul Benedict
Fix For: 1.4.0
To better align with Struts 2 and other modern frameworks, provide a new
attribute on ActionConfig for an instantiation policy. Initial thoughts are:
singleton="true|false" and default to true.
Example: If action A uses class X as a singleton, and class B uses class X as a
prototype, and class C uses class X as a singleton, both A and C will share the
instance, while B will receive a new action per request.
It appears only minimal changes are needed. AbstractCreateAction delegates to
abstract method getAction. The concrete method in CreateAction simply needs to
first check the ActionConfig property and (a) create a new form and not cache
for prototypes or (b) existing functionality today for singletons.
