Hi all,

I'm trying to write localized content in a service builder generated field.

The code I have up to now is (for field5 of the default foo entity defined as <column name="field5" type="String" localized="true"/>):

        Set<Locale> locales = LanguageUtil.getAvailableLocales();

        Map<Locale, String> map = new HashMap<Locale, String>();

        for (Locale locale : locales) {
            String languageId = LocaleUtil.toLanguageId(locale);
            String xxx = "field5";
            String localeParameter = xxx.concat(StringPool.UNDERLINE).concat(languageId);
            String yyy = ParamUtil.getString(actionRequest,localeParameter);
            map.put(locale, yyy);
        }
        
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        XMLEncoder xmlEncoder = new XMLEncoder(bos);
        xmlEncoder.writeObject(map);
        xmlEncoder.flush();

        String field5 = bos.toString();

But the loop to assign values to map gives these errors:

java.lang.InstantiationException: java.util.Locale
Continuing ...
java.lang.Exception: XMLEncoder: discarding statement HashMap.put(Locale, "");
Continuing ...
java.lang.InstantiationException: java.util.Locale

What I'm doing wrong?
