Empty and null strings

Hi!

This must be a "most asked" question, but here goes... I'm a little confused with empty and null strings, in what relates to WOTextField component.

Why does a WOTextField value is null when there is no text? Shouldn't it be an empty string? The empty string and null objects are two distinct things for the model, right?

  Yours
