[jira] [Commented] (WW-4105) Struts2 raise
java.lang.ClassCastException when Result type is chain
[ https://issues.apache.org/jira/browse/WW-4105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15979371#comment-15979371 ]

WW-4105 Considers config time class in actions chain
I think it is `ready for merge` and does not break backward compatibility. The added `bean` attribute is and should be optional always.
If you agree and merged this, then [784bb23](https://github.com/yasserzamani/struts/commit/784bb235e2ffcfcd7a5f2f47965ca0183e952ddd) will be a base for other possible enhancements like:
- Considering config time class of the action in parameters interceptor enhances S2 security (details already have been submitted to `security@struts.apache.org`).
- Considering config time class of the action in json result has similar impacts (prevents action information to be leaked to attacker).
What do you think?
# Documentation
Mainly, this is about how to deal when run time class of the action is not same as the config time, e.g. when action is proxified with a 3rd party technology or when the creation of action is with object factory. At this point, operating S2 inside that technology or object factory makes problems or potential security issues. So S2 always needs to know config time class of the action to operate in it's own borders only.
Currently S2 uses `class` attribute for both config time class or bean name of the action inside object factory. When the user uses `class` attribute as a bean name, S2 looses this information, config time class of the action. This PR gives it back to S2 by [784bb23](https://github.com/yasserzamani/struts/commit/784bb235e2ffcfcd7a5f2f47965ca0183e952ddd) and presents a resolution for [WW-4105](https://issues.apache.org/jira/browse/WW-4105) as an example which shows how to consider config time class of the action in sensitive places.
