Description

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.
