play 1.2.4-----scaffold module problem:getting error

[suman adak]

Hi,

I added scaffold module in my application. I created a very simple domain class called Vendor.

package models;

import javax.persistence.Entity;

import play.db.jpa.Model;

@Entity

public class Vendor extends Model {  

    public String vendorName;

    public String phone;

    public String address;

}

While saving, I got this error

Template execution error (In /app/views/Vendors/_form.html around line 25)

Execution error occured in template /app/views/Vendors/_form.html. Exception rai

sed was MissingPropertyException : No such property: id for class: models.Vendor

.

play.exceptions.TemplateExecutionException: No such property: id for class: mode

ls.Vendor
