Grails validation: get message from error object as string

I have a validating command object in my controller method and when validation fails I want to print out the error message rendered as JSON:

def doSomething(MyCommand cmd) {
    if (cmd.hasErrors()) {
        render ([success: false, error: cmd.errors.getFieldError("myfield")] as JSON)
    }
}

This prints the JSON representation of the field error, but I just want to print the resolved error message. How can I achieve that?

Thanks!

The post is old, but here is my solution.

import org.codehaus.groovy.grails.commons.ApplicationHolder

def myCommand = new MyCommand()

myCommand.errors.reject('Foo error')
myCommand.errors.reject('Bar message')
myCommand.errors.reject('myCommand.myfield.nullable')

def appHolder = ApplicationHolder.application.mainContext.getBean('org.codehaus.groovy.grails.plugins.web.taglib.ApplicationTagLib')
def list = myCommand.errors.allErrors.collect{appHolder.g.message([error: it])}
list

Result:

["Foo error","Bar message","Property myfield cannot be null"]

This works for me

def errMsgList = domainClassObj.errors.allErrors.collect{g.message([error : it])}

Ah, I resolved this problem:

render ([success: false, error: message(error: cmd.errors.getFieldError("myfield"))] as JSON)

Before, I got an error using message(), maybe I had made another mistake then.
