Support for "no value"
----------------------

         Key: RCP-182
         URL: http://opensource.atlassian.com/projects/spring/browse/RCP-182
     Project: Spring Framework Rich Client Project
        Type: New Feature
  Components: Binding System  
 Reporter: Oliver Hutchison
 Assigned to: Oliver Hutchison 


We need a way to tell a form model that it currently represents "no value". A form with "no value" being a form that does not have a backing object. 

The question is how do we represent this? I'd imagine we could simply introduce a new class NoValue which when set into a form model causes all of the form model's property values to also become NoValue, you'd then need some logic in the bindings to detect no value so that they can modify themselves to display "nothing" however is appropriate.

This idea can also be extended to the form's properties .
