Don Brown commented on WW-2046:
-------------------------------
Try a later version like 2.0.11 and let us know if it is still a problem.
> Radio map to map type conversion now fails
> ------------------------------------------
>
> Key: WW-2046
> URL: https://issues.apache.org/struts/browse/WW-2046
> Project: Struts 2
> Issue Type: Bug
> Components: Views
> Affects Versions: 2.0.8
> Environment: freemarker
> Reporter: Jasper Rosenberg
> Assignee: Don Brown
> Fix For: 2.0.12
>
>
> Example:
> Action has get/set for:
> private Map<String, String> myMap = new HashMap<String, String>();
> Template:
> <@s.radio name="myMap['name']" list='[EMAIL PROTECTED]@{"Opt.":"Opt.",
> "Std.":"Std.", "":"N/A"}' theme="simple"/>
> In struts 2.0.6, when I selected a value in the radio button, it would
> correctly create a map from String to String.
> In struts 2.0.8, when I selected a value in the radio button (any of the
> three), it would incorrectly create a map from String to String[].
> Not sure if this is due to a change in 2.0.8, or in XWork 2.0.3.
> I have a second case that again used to work in 2.0.6, that now fails in
> 2.0.8 where the map key is also not converting correctly:
> public class ReviewPicturesAction ... {
> /** New picture status approve. */
> public static final String APPROVE = "A";
> /** New picture status deny. */
> public static final String DENY = "D";
> /** New picture status prefer. */
> public static final String PREFER = "P";
> private Map<Long, String> pictureMap = new HashMap<Long, String>();
>
> // getter/setter
> ...
> }
> <@s.set name="statusMap" value="[EMAIL PROTECTED]@[EMAIL
> PROTECTED]@APPROVE:'A',@[EMAIL PROTECTED]:'P',@[EMAIL PROTECTED]:'D'}"/>
> <@s.radio name="pictureMap[5]" list="statusMap" theme="simple" value='@[EMAIL
> PROTECTED]'/>
> In this case the key in the map ends up as "62051" (String) rather than
> 62051L (Long), and the value is again a String[].
