Description

In the documentation, there is a way to repopulate a field with the original user input when there is a conversion error:

http://struts.apache.org/2.3.3/docs/conversion-validator.html

However, this does not work if you try to apply l10n to user input: integers, dates, real numbers.

Current workaround:

In jsp:

<s:textfield key="user.born" value="%{getFormatted('format.number','user.born')}" />

In BaseAction:

    public String getFormatted(String key, String expr) {

        Map<String, Object> conversionErrors = ActionContext.getContext().getConversionErrors();
        if (conversionErrors.containsKey(expr)) {
            String[] vals = (String[]) conversionErrors.get(expr);
            return vals[0];
        } else {
            final ValueStack valueStack = ActionContext.getContext().getValueStack();
            final Object val = valueStack.findValue(expr);
            List<Object> valList = new ArrayList<Object>();
            valList.add(val);
            return getText(key, valList);

        }
    }
