Christoph Nenning updated WW-4224:
----------------------------------
Attachment: redirect-with-collection-parameters.patch
> Collection Parameters for RedirectResults
> -----------------------------------------
>
> Key: WW-4224
> URL: https://issues.apache.org/jira/browse/WW-4224
> Project: Struts 2
> Issue Type: Improvement
> Components: Core Actions
> Affects Versions: 2.3.15.3
> Reporter: Christoph Nenning
> Priority: Minor
> Attachments: redirect-with-collection-parameters.patch
>
>
> 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.
