>             Project: Struts 2
>          Issue Type: Improvement
>          Components: Core Actions
>    Affects Versions: 2.3.15.3

> In some applications I have actions with a list member. That may be filled e.g. via checkboxlist. As we use Redirect-After-Post I want all list-elements to be present in redirect URL.
> The framework provided ServletRedirectResult uses 
> StrutsResultSupport.conditionalParse()
> which in turn uses 
> TextParseUtil.translateVariables()
> to resolve variables present as parameter values of a redirect result.
> Those methods convert the found object into String. When a collection is found just toString() is invoked. That is not quite useful.
> I would like to duplicate the URL-parameter-name for each element in the found collection.
> Therefore I added new Methods (with javadoc and tests):
> - StrutsResultSupport.conditionalParseCollection()
> - TextParseUtil.translateVariablesCollection()
> and using them in ServletRedirectResult.
> URL building itself does already support collections as paramter values.
> The problem was just that TextParseUtil forced the collection found on ValueStack into a string.
