model update error : hide exception

[Dave <ja...@yahoo.com>]

During model update phase, if a setter method throws an exception,
  For example, setUsername(String username)
   
  Faces  will display a message:
        Conversion Error "username": Error during model data update
   
  and in the meantime display a stack trace on server side console.
   
  How to 
  1. replace the message with  "Invalid user name: xyz"?
  2. prevent displaying stack trace on server side since it is a normal error caused by clients ?
   
  Thanks for help!

I would suggest that you use a validator before update the model. This could be
either a method in your backing bean or a separate class. Or, if appropriate,
you could use some of the predefined validators (like Tomahawk's
validateRegExpr).
Thus you'll have control over the message.
