I have to use a file form element that is not required. What happens if the field is not populated? What value is returned by getValue()? I'd like to set a default value (the id of file in my table) that is used when the file is not uploaded, so that if the user does not submit anything during an editing of an entity, the corresponding file field does not change. I'm looking at getValue() because it's used by Zend_Form::getValues() (what I am calling in my controllers). What validators/methods should I subclass? Thanks in advance.
