My opinion: a function that is called getstring() should always  
return a string... even if it is null, I'm asking to GET a STRING.  
Waiting for Ruslan...

We can even discuss on point 1) why vfield.value on an empty field  
and on a Null field always results the wrong <Null> value (that  
should be <Void>): shouldn't it give an empty string on an empty  
varchar/text field and <Void> on a Null varchar field?
