How render custom error messages?

Question

I have a domain class :

package x

class User {

    transient springSecurityService

    String username
    String password
        //other stuffs.
    static constraints = {
    username blank: false, unique: true
    password blank: false
    email blank: false, email:true
    }
}

This is the class that I used for Spring security. In my /register/index page I need custom error messages, so I added these lines into message.properties:

x.User.username.unique=Username already exists. Please use other username.

But that doesn't seem to be working. I get only this error message : Property [{0}] of class [{1}] cannot be null

Even though I pass some value into my username column I still get this error message. I'm confused with it. How this /register/index comes from?

Where I need to change the error message?

Thanks in advance.

Where are you seeing that message? Can you add the relevant bit of your GSP or controller code? — Ian Roberts, Aug 07 '12 at 08:14

The problem is the way you've declarated the message code, it doesn't fallow the convention. Take a look Validation and Internationalization. Here you can find that the right way is
[Class Name].[Property Name].[Constraint Code]
So your constraint should be

user.username.unique=Username already exists. Please use other username.
