-----------------------------

             Summary: provide better documentation and / or functionality for localization
of struts2 tag elements (select, radio, etc.)
                 Key: WW-4295
                 URL: https://issues.apache.org/jira/browse/WW-4295
             Project: Struts 2
          Issue Type: Bug
    Affects Versions: 2.3.16
            Reporter: adam brin


The <@s.text> macro is very useful for localization of text values.  The <@s.textfield
tag also takes a "key" > but, the select, radio, and checkbox options don't have good options
for localization.  One option raised on the list and identified in a few places is to construct
a separate map of variables that have been localized in Freemarker and use that for localization
(https://stackoverflow.com/questions/5548104/struts-select-tag-localization-implementation/17258640#17258640)...
this does not seem sustainable or maintainable. Two possible methods for addressing this might
be:

# update the documentation to better identify how to localize these values in the "approved"
way
# implement a listKey parameter that like the textfield implementation or other implementations
might call getText() on the key prior to rendering


{code:title=Example Implementation for Radiobutton}
    <#if parameters.listKey??>
        <#assign itemValue><@s.text name="${stack.findString(parameters.listKey)}"
/><#rt></#assign>    
    <#elseif parameters.listValue??>
        <#assign itemValue = stack.findString(parameters.listValue)/>
    <#else>
        <#assign itemValue = stack.findString('top')/>
    </#if>
{code}
