Aymeric Levaux commented on WW-2045:
------------------------------------
Ok this fixes the rendering of the radio map.
But I still get a conversion error on form submit when the selected value is ""
(to get a null) .
This is due to the method convertFromString in
com.opensymphony.xwork2.util.EnumTypeConverter that does not check for empty
string before calling Enum.valueOf.
Simply adding
if(value == null || "".equals(value)){
return null;
}
makes it for me. I didn't checked this thoroughly so it might requires more
investigations.

> Project: Struts 2
> Issue Type: Bug
> Components: Views
> Affects Versions: 2.0.8
> Environment: freemarker
> Reporter: Jasper Rosenberg
> Assignee: Don Brown
> Fix For: 2.0.10
>
>
> In my action, have setter getter for myMap property:
> private Map<String, String> myMap = new HashMap<String, String>();
> <@s.radio name="myMap['name']" list='[EMAIL PROTECTED]@{"Opt.":"Opt.",
> "Std.":"Std.", "":"N/A"}' theme="simple"/>
> In struts 2.0.6, if "name" had no value in the map, then "N/A" would be
> selected.
> In struts 2.0.8, if "name" has no value in the map, then no option is
> selected.
> I have tried variations on the list such as '[EMAIL
> PROTECTED]@{"Opt.":"Opt.", "Std.":"Std.", null:"N/A"}' to work around this
> issue without luck.
