Grails Spring Security UI RegisterController覆盖

Question

我对Grails 2.4.3和Spring Security RC2的升级感到有些麻烦......我可能只是遗漏了一些东西，但感激不尽。

我在这里覆盖了RegisterController：

def register(RegisterCommand command) {

    if (command.hasErrors()) {
        render view: 'index', model: [command: command]
        return
    }

    String salt = saltSource instanceof NullSaltSource ? null : command.username

    //def info = Info.findByName(command.info.toString().replace("[", "").replace("]", ""))
    def info = Info.findByName(params.info).toString().replace("[", "").replace("]", "")

    def user = lookupUserClass().newInstance(email: command.email, username: command.username,
            accountLocked: true, enabled: true, info: info, location: params.location)

    RegistrationCode registrationCode = springSecurityUiService.register(user, command.password, salt)
    if (registrationCode == null || registrationCode.hasErrors()) {
        // null means problem creating the user
        flash.error = message(code: 'spring.security.ui.register.miscError')
        flash.chainedParams = params
        redirect action: 'index'
        return
    }

    String url = generateLink('verifyRegistration', [t: registrationCode.token])

    def conf = SpringSecurityUtils.securityConfig
    def body = conf.ui.register.emailBody
    if (body.contains('$')) {
        body = evaluate(body, [user: user, url: url])
    }
    mailService.sendMail {
        to command.email
        from conf.ui.register.emailFrom
        subject conf.ui.register.emailSubject
        html body.toString()
    }

    render view: 'index', model: [emailSent: true]
}

class RegisterCommand {

String username
String email
String password
String password2

List info = Info.findAll("from Info as d where d.name!=?", ['Super Admin']).toList()

def grailsApplication

static constraints = {
    username blank: false, validator: { value, command ->
        if (value) {
            def User = command.grailsApplication.getDomainClass(
                    SpringSecurityUtils.securityConfig.userLookup.userDomainClassName).clazz
            if (User.findByUsername(value)) {
                return 'registerCommand.username.unique'
            }
        }
    }
    email blank: false

    password blank: false, nullable: false
    password2 validator: RegisterController.password2Validator
}

}

以下是我的GSP代码片段

    <div class="control-group">
        <label class="control-label" for="selectDepartment">Info</label>
        <div class="controls form-field-pad">
            <g:select name="info" from="${command.info.name.unique()}" labelCode='Info'
                      labelCodeDefault='Info' value="${info}" noSelection="['':'-Choose your Info-']" data-trigger="change" data-required="true" data-required-message="You must select Info"/>
        </div>
    </div>

现在，如果我使用对Info的引用删除我的附加代码，那么用户将被正确存储并发送电子邮件...但是我收到以下错误：

register.index: [action:index, controller:register]

有什么想法吗？提前谢谢！
