Don Brown resolved WW-1960.
---------------------------

       Resolution: Fixed
    Fix Version/s:     (was: 2.0.12)
                   2.1.0
         Assignee: Don Brown

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 :)

> 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.
