Resolution: Fixed
Fix Version/s: (was: 2.0.12)

Fixed in 2.1 as it could break existing applications. All values are now
converted into string arrays, whether they want to be or not :)
> action tag violates ParameterAware contract
> -------------------------------------------

> Key: WW-1960
> URL: https://issues.apache.org/struts/browse/WW-1960
> Project: Struts 2
> Issue Type: Bug
> Components: Actions
> Affects Versions: 2.0.6, 2.0.7, 2.0.8, 2.0.9, 2.0.10
> Environment: linux,jdk1.5,tomcat5.5
> Reporter: David Mansfield

> Priority: Minor
> Fix For: 2.1.0
>
>
> the javadoc for ParameterAware states that the values of the map are all
> java.lang.String[], in other words it is a Map<String,String[]>. Indeed,
> when hitting an action via a 'genuine' http request, this is true. However,
> when hitting the action via the action tag, the values in the map are String,
> not String[]. The bug appears to be possibly line 177 in ActionComponent:
> 176: if (parameters != null) {
> 177: newParams.putAll(parameters);
> 178: }
> The parameters of the component are Map<String,String> and therefore cannot
> be combined directly into the ActionContext.getParameters map.
