>             Project: Struts 1
>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 1.3.8
>         Environment: Using with AndroMDA 3.2. Windows XP, Java 5.0

> The method below is wrong, because if a bean has a java.lang.Double field the validation is not working. The getValueAsString returns anything if the field is set. But if the user types sharacters in a double field the bean has a NULL value in that field, so this method returns null, that is wrong, because the typed string is not visible any more.
> Wrong method:
>     private static String evaluateBean(Object bean, Field field) {
>         String value;
>         if (isString(bean)) {
>             value = (String) bean;
>         } else {
>             value = ValidatorUtils.getValueAsString(bean, field.getProperty());
>         }
>         return value;
>     }
> Good method to use:
>     private static String evaluateBean(Object bean, Field field, HttpServletRequest request) {
>         String value;
>         if (isString(bean)) {
>             value = (String) bean;
>         } else {
>             value = request.getParameter(field.getKey());
>         }
>         return value;
>     }
> PS: Can't send a patch, sorry!
