Don Brown commented on WW-2635:
-------------------------------
Actually, please hold off on this and all scope-related ones. I want us to
work on creating a unified solution to scoping issues in 2.2 to help bring
together all these little one-off solutions.

> Project: Struts 2
> Issue Type: New Feature
> Components: "New" API

> I have developed a FlashResult / FlashInterceptor pair to implement "flash"
> scope in a way that follows the usual Struts2 principles and respects its
> "feel".
> It basically works like the ServletActionRedirectResult except that instead
> of converting all extra parameters to strings and adding them as HTTP
> parameters in the redirect URL, it creates a HashMap using these parameter
> key/value pairs with no conversion and stores it in the user session. On the
> next HTTP request the FlashInterceptor, if properly added to the interceptor
> stack, will retrieve this map and copy the map entries to the target action
> using the parameter keys. It should work for all data types.
> To function correctly this approach assumes that bug WW-2170 is fixed. The
> implementation also borrows a lot from the ServletActionRedirectResult and
> some refactoring should
> be done.
> While there may be issues with flash scope in general with regards to
> repeated GETs being inconsistent, there are some valid use cases such as when
> saving messages to be displayed after a redirect. I think it's good for the
> developer to have this tool and it could make a nice addition to the Struts2
> code base.
