【问题描述】：
我在这个 GORM 继承问题上被阻止了，我很感激一些新的眼睛来看看这个问题。 （我使用 Grails 1.3.2）
我有一个基础抽象类...
abstract class MaintenanceSchedule {
static belongsTo = [ maintenanceTask:MaintenanceTask ]
}
我想像这样扩展它......
class OneOffSchedule extends MaintenanceSchedule {
Date scheduleDate
static constraints = {
scheduleDate(nullable:false)
}
private static OneOffSchedule getReferenceOneOffSchedule() {
return new OneOffSchedule(scheduleDate:new Date())
}
}
当我尝试运行我的应用程序时，我得到以下堆栈跟踪。
