If from one view a user enters some invalid data, e.g.:

    E-mail: [email protected]    

then i want the controller to:

• not place the data into the model
• color the text box reddish
• not allow the user to save

But it's possible that if the user enters the same invalid data in a different view i want the controller to:

• place the data into the model
• color the text box reddish
• allow the user to save

But it's possible that if the user enters the same invalid data in a different view i want the controller to:

• place the data into the model
• color the text box bluish
• allow the user to save

And it's possible that another view will:

• place the data into the model
• leave the text box uncolored
• allow the user to save

And it's possible that another view will:

• auto-correct the data, placing it into the model
• color the text-box reddish
• allow the user to have

And it's possible for another view to:

• auto-correct the data, placing it into the model
• update the view with the new data
• color the text-box bluish
• allow the user to save

[ad infinitum]

Without using n-controllers for n-views, how do i do this?
