视图中未呈现验证错误

class Person {
    String fullName
    List telephones = []

    static hasMany = [telephones : Telephone]

    static constraints = {
        fullName(size:3..50, blank:false, nullable:false)
    }
}

然后是一个子类:

class SalesAdvisor extends Person{
    Float comission //In percentage
    Portfolio customerPortfolio
    Inventory inventory

    static constraints = {
        comission(range:0..100, scale:2, nullable:false)
        customerPortfolio(nullable:false) 
        inventory(nullable:false)
    }
}

在SalesAdvisorController中,我保存SalesAdvisor实例:

def save = {
    def portfolio = new Portfolio()
    def inventory = new Inventory(name:'${params.fullName}Inventory', description:"${params.fullName}'s Inventory")
    params.customerPortfolio = portfolio
    params.inventory = inventory
    def salesAdvisor = new SalesAdvisor(params)

    if(!salesAdvisor.hasErrors() && salesAdvisor.save()){
        log.info("New instance of SalesAdvisor saved.")
        redirect(action:show, id:salesAdvisor.id)
    }else{
        log.error("There was an error saving the sales advisor.")
        salesAdvisor.errors.allErrors.each{
        println it.code
    }
    render(view:'create', model:[salesAdvisor:SalesAdvisor])
  }
}

为了显示任何错误,在“创建”视图中,我有:

<g:hasErrors bean="${salesAdvisor}">
    <div class="errors">
        <g:renderErrors bean="${salesAdvisor}" as="list" />
    </div>
</g:hasErrors>

验证似乎工作正常。但是,如果我为佣金字段提交一个字符串而不是一个浮点数,在日志中我可以看到“typeMismatch”,但是视图没有呈现任何内容!message.properties文件具有类型不匹配的默认条目。对于fullName字段也是一样,在日志中我可以看到“null”和“blank”错误,但是视图没有呈现任何内容。

我猜这更多的是视图的错,而不是控制器或域的错,因为单元测试的行为应该是这样的。
