Question

我有三个这样的课程：

度假：

包mnm

class Holiday {
    //Date start
    //Date end
    HolidayStatus status
    String justification
    static belongsTo = [ user : User ]
        static constraints = {
        status(nullable:true)
        user(nullable:true)
        //start(nullable:true)
        //end(nullable:true)
        }
}

用户：

package mnm

class User {
    String login
    String password
    static hasMany = [ holidays : Holiday ]
        static constraints = {
    }
}

HolidayStatus ：

package mnm

class HolidayStatus {
    String name
    static belongsTo = [holiday :Holiday ]
        static constraints = {
        name(blank:false)
    }
}

我写了一个像这样的集成测试：

void testWithBelongsTo() {  
        def user1 = new User(login:"anto", password:"secret")
        assert user1.save()
        def holiday1 = new Holiday(justification:"went to trip")
        assert holiday1.save()
        user1.addToHolidays(holiday1)
        assertEquals 1, User.get(user1.id).holidays.size()
        user1.delete()
        assertFalse User.exists(user1.id)
        assertFalse Holiday.exists(holiday1.id)
    }

它完美无缺，测试正在通过。当我像这样更改我的Holiday课程时：

class Holiday {
    Date start
    Date end
    HolidayStatus status
    String justification
    static belongsTo = [ user : User ]
        static constraints = {
        status(nullable:true)
        user(nullable:true)
        start(nullable:true)
        end(nullable:true)
        }
}

（即添加start, end类型的Date新字段。）

现在，如果我将测试改为这样的话：

void testWithBelongsTo() {  
        def user1 = new User(login:"anto", password:"secret")
        assert user1.save()
        def holiday1 = new Holiday(justification:"went to trip", start: new Date("05/01/2010"),end: new Date("05/01/2011"))
        assert holiday1.save()
        user1.addToHolidays(holiday1)
        assertEquals 1, User.get(user1.id).holidays.size()
        user1.delete()
        assertFalse User.exists(user1.id)
        assertFalse Holiday.exists(holiday1.id)
    }

我收到的错误是这样的：

这是怎么回事？我犯了哪个错误？这导致其他测试甚至失败！

提前致谢。
