> The list of values of the request property can never have the length of null
> - RequestProperty.getStringValues() ensures this, and it also does not make
> any sense with form posts, since a request parameter must always have at
> least one value, otherwise it would simply not exist in the request. So this
> code is superfluous (also for single-value property handling):
> } else if (values.length == 0) {
> // do not create new prop here, but clear existing
> if (parent.hasProperty(prop.getName())) {
> response.onModified(
> parent.setProperty(prop.getName(), "").getPath()
> );
> }
