Don Brown closed WW-419.
------------------------

       Resolution: Implemented

This capability has been implemented in WebWork 2, and since this JIRA is only concerned with post WebWork 2, I'm closing the ticket.

> I am sure I speak for most webwork 1.x users when I talk of the pain of redirects.  The necessity of having the action construct the redirect (albeit through the use of the RedirectAction) seems to be grossly out of step with the way that forwards (ie views) are done.  Redirects are a common requirement wherever you have an action which changes state - you want to redirect to another page to avoid nastiness if the user clicks refresh (like debitting your credit card again for example).
> What I am embarking on is a change that would allow this to be handled seamlessly by simply returning a result from the action.
> The actions.xml would now support entries of the form:
>     <action name="portfolio.AddHolding" alias="AddHolding">
>         <view name="input">/portfolio/addholding.jsp</view>
>         <view name="success">
>             <url redirect="true">ViewPortfolio.action</url>
> 	    <param name="portfolioId" value="portfolioId" />
>             <param name="currency" value="'USD'" />
>         </view>
>     </action>
> The param tags define what parameters are passed with the redirect, the values being expressions that will be evaluated across the ValueStack when the dispatcher processes the results.
> I've started work on this, but I'd be interested in any comments from anyone.
