TextProvider in ActionSupport not available after Serialization
---------------------------------------------------------------
Key: WW-2298
URL: https://issues.apache.org/struts/browse/WW-2298
Project: Struts 2
Issue Type: Bug
Components: Core Actions
Affects Versions: 2.0.9
Environment: Struts 2.0.9
Reporter: Robert-Jan Westerhof
Priority: Minor
ActionSupport is TextAware, and has a TextProvider to support this
functionality.
However, the TextProvider inside ActionSupport is transient and final
(instantiated only once).
After Serialization of the action, the TextProvider is null, and there is no
way to re-instantiate it
(it just spawns NPEs after this).
Suggested patch:
remove final modifier from TextProvider field, and add a private
getTextProvider() method that
performs null-check / lazy instantiation via the factory.
