-------------------------------------
Summary: 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
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.
