> It seems to be impossible transmit the empty string as a value: In the HTTP request
>   http://.../turbine/...?aaa=123&bbb=&ccc=456
> the parameter bbb is ignored.
> If you look at org.apache.turbine.services.intake.model.Field.init(ValueParser pp) you find:
>         if (pp.containsKey(getKey()))
>         {
>             if (isDebugEnabled)
>             {
>                 log.debug(name + ": Found our Key in the request, setting Value");
>             }
>             if (StringUtils.isNotEmpty(pp.getString(getKey())))
>             {
>                 setFlag = true;
>             }
>             validate();
>         }
>         else if (pp.containsKey(getValueIfAbsent()) &&
>                 pp.getString(getValueIfAbsent()) != null)
>         {
>             pp.add(getKey(), pp.getString(getValueIfAbsent()));
>             setFlag = true;
>             validate();
>         }
> The StringUtils.isNotEmpty() condition (line 342) prevents that a field can take up the empty string as its value.
