Description

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.
