How to compare the value of two fields

[sergio11]

Is it possible to create a validator to compare the value of two fields?.

I wanted to implement a validator that compares the value of PasswordClear and ConfirmPassword.

With the Bean Validation API I have implemented a validator of this style

@FieldMatch (first = "passwordClear", second = "confirmPassword", message = "{user.pass.not.match}")

Where can I find documentation on how to implement custom validators?

Thanks in advance.

We don't have the validator now. Maybe we need a 'CompareAttribute' such as:

    //
    // Summary:
    //     Provides an attribute that compares two properties.
    [AttributeUsage(AttributeTargets.Property, AllowMultiple = false)]
    public class CompareAttribute : ValidationAttribute
    {
        //
        // Summary:
        //     Initializes a new instance of the System.ComponentModel.DataAnnotations.CompareAttribute
        //     class.
        //
        // Params:
        //   otherProperty:
        //     The property to compare with the current property.
        public CompareAttribute(string otherProperty);

        //
        // Summary:
        //     Gets the property to compare with the current property.
        //
        // Returns:
        //     The other property.
        public string OtherProperty { get; }
        //
        // Summary:
        //     Gets the display name of the other property.
        //
        // Returns:
        //     The display name of the other property.
        public string OtherPropertyDisplayName { get; }
    }

Can you contribute codes about it? And I will merge it.
